I am planning to setup a home network with Ubuntu.the home network consists of ~3/4 computers; a mediaserver (reelbox) and 2 more PCs.Can I setup the server as a DSL router and get rid of my modem/router I have right now?
View 3 RepliesI have been searching google for a while now and have not found exactly what I am looking for. I would like to use my fresh install of ubuntu server 11.04 as my router/gateway for my home. I am not an expert at linux by any means but I can usually figure stuff out. I believe I need iptables, bind, and a few others probally. It eventually will also be a samba server but I have done a little with samba before. I do have 2 network cards, my router at the moment is starting to die and would love to have a more powerful router. I would also like to figure out how to do port forwarding in the router, as well as be able to see the load on the network cards. Maybe there is a program to show usage by user? As well as be able to do packet pritorization.

At the present my DHCP is done by my router and I want to set up the PXE server on my main PC.My router can re-direct traffic types based on ports (UDP or TCP) to an IP but can't do the bit about directing the pxe loader name (and I really don't want to ssh into it and start messing about there)If I redirect the port (what ever it may be, help required here) how would I go about setting up the Ubuntu PC to do the load and pass back to the PC trying to PXEboot?
View 1 Replies View RelatedI'm having trouble getting my network set up the way that I want it/had it. You see, when I first set up my network, I just had my cable modem going directly to my standard wired router (A D-Link DI-604), which had DHCP,and was connected to all of the computers on my network. I had one switch hooked up to one of the ports of the router, but this was a regular switch, and it would not try to assign IP addresses, it would just pass through the DHCP info as I wanted.
Now however, my network setup has changed. My room mate and I both got laptops, and we decided that we wanted to have wireless access so we didn't have to constantly plug in to the router.
Now my network is set up like this: The modem is hooked up to the router(DI-604), which is hooked up on the LAN side to our computers, our switch (which is hooked up to 3 more computers), and to a wireless router card (A Gigabyte GN-BC01).
The wireless router card has two jacks for ethernet. One for WAN, and one for LAN. The LAN side we have plugged only into the computer in which the card is installed.
Now the problem is this: The wireless router card comes with DHCP by default, and it's assigning addresses to the laptops and to the computer hat it's in, and worse, the IP addresses are on a different subnet than that of the main dlink router. The Main (dlink) router assigns addresses from 192.168.0.1 (itself) to 192.168.0.254, while the wireless router card assigns addresses from 192.168.1.1 to 192.168.1.254 (itself).
Because of this, I cannot access services on the wireless network from my wired network or vice versa. The first thing I tried was setting the card to assign addresses from 192.168.0.12 to 192.168.0.253, however it just said "internal error" when I tried to do this. I decided that this may be because it sees that it was being assigned an address on it's WAN side on the same subnet. So the next thing I tried was disabling DHCP and setting the "LAN IP Address" to 192.168.0.12, hoping that the DHCP would just go through the card, like a switch. I would have set the LAN IP address to be assigned by DHCP, but this was not an option, so I decided that'd be the best thing to set it to.
Once again however, setting the LAN ip address to an address on the same subnet as that of the IP assigned to it's WAN side caused it to report an "internal error". I verified that this was the issue by setting the LAN address to several other private IP addresses to test (I.E. 10.0.0.1, 192.168.3.1, 192.168.5.12).
My question then really is: How do I set up both routers so that I can access services and computers from each network from the other network. Should I set them with different subnets and set the gateway on the wireless network to the main router? To the wireless router card? Should I put them on the same subnet? Will it know how to communicate?

I'm going to start a new thread because previous searches have not totally satisfied my question. I've read all day about doing this but each inquiry leads to discussion of configuring the router. I am also not network savy. I would like to set up an FTP server on my home computer (presently Ubuntu 8.10). I have only one computer. I am using DSL with my telephone line for internet connection. I do not use a router.
Is it possible to do this with no router and only a DSL ISP connection?
how to setup ubuntu as router. i already try to setup but it doesn't work.
my situation is to create ubuntu as router. i have two network card etho and eth1. i want to create eth0 in DMZ and eth1 only can only access in internal.
I have multiple devices in my garage that need internet connectivity. I have my main Netgear router inside the house. I have a computer running Ubuntu in the garage with dual NICs.
Here's a map of how I have it setup now: [URL]
Here's my /etc/network/interfaces:
Code:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.1.60
netmask 255.255.255.0
gateway 192.168.1.1
auto eth1
iface eth1 inet static
address 192.168.1.5
network 192.168.1.0
netmask 255.255.255.0
broadcast 192.168.1.255
I was trying to keep everything on the same subnet. Eth0 is the external NIC, connected to the router in the house. eth1 is the internet NIC, which would go out to the devices in the garage. Now, I know it would be easiest to just connect a switch up and run all the devices in the garage off that switch. But the switch I have is a 10/100, and my network in the house is gigabit, and I want the PC in the garage to have gigabit access... which is why I'm doing this dual NIC setup and using the PC as a router, then the other devices in the garage will be 10/100.
In addition, I used the shell script as described in this article: [URL] to setup iptables. I also uncommented the net.ipv4.ip_forward=1 line in /etc/sysctl.conf. What am I doing wrong here? None of the devices in the garage that I connect up to the Ubuntu PC are getting connectivity. None are getting a DHCP lease from the main router in the house. The Ubuntu PC itself has internet access just fine though.
I've just finished installed a mail server with Fedora 12 + postfix + courier. I also have Squirrelmail and ISPConfig3 installed. The mail server is behind a router. I have [URL] pointed to the static IP at my router. My ISP has opened port 25 & 110 for me and my router has these 2 ports forwarded to my mail server (192.168.0.100).Workstations in local network can connect to my mail server and send emails with no problem but cannot receive emails from outside. I tried an email dossier and it saids connection timed out on smtp session. Do I need to include my static IP somewhere in the configuration so that it communicates to the world properly?
View 4 Replies View RelatedI am thinking of moving the router behind a server and connecting the server directly to the internet via a modem. Are there any security issues related to doing this? or other things I should be aware of. Iptables are implemented on the server blocking access on unused ports.

Here's my setup. I have the modem connected to a switch (wired) that connects 2 PCs to the internet (one desktop, one server, both wired).

I would like to setup a Linux Router with Fedora. Here is what I have and would like to do...
Email filter device is on the LAN at 192.168.x.3. I need to provide SNAT to that device from both T1 interfaces...
All outgoing traffic will route through DSL except for traffic destined for addresses on either eth0 or eth1 (web sites).
I assume I would need the following:
I also assume I would need to setup iptables with FORWARDs for the 192.x.x.x networks to eth3.
What I am not sure how to do, is properly setup the incoming redirections so that the email filter can be access from both eth0 and eth1 by different IP addresses.
I've got an Ubuntu box set up as a router and wifi hotspot. I can access the internet and any website using this box. I can connect a laptop to my wifi access point, and connect to both the router box and the internet. I'm writing this message from it. If I access either hsbc Hong Kong internet banking or speedtest.net from my laptop I can't connect. Every other site I've tried is fine. What could be causing this? I don't know where to start. I've set up the firewall rules and routing tables, so I vaguely know what I'm doing... but clearly not enough to debug this issue.

View 4 Replies View RelatedI would like to setup a qmail server for learning purposes (if you strongly feel Postfix is better, feel free to let me know). When I started setting up qmail (using Life with qmail), it suggested that having a DNS is the best approach. In the spirit of learning, I decided then to create another server for DNS only, and use that for qmail.
My problem is that, as this is a home installation, the internet is behind a Netgear DG834Gv5 router, on a DSL line that has a dynamic IP address. I am using DynDNS, but also don't mind having to update any DNS entries to keep up with the change, this is not exactly a production-grade setup.
In addition, I also have access to another DNS server where I can create authoritive entries for any domain I register. I have done that for a domain, and would like to point part of that to my home DNS so that I can learn.
So essentially, I would like to have a new zone for home.mydomain.org on my home DNS so that I can create new entries for *.home.mydomain.org such as qmail.home.mydomain.org etc. there.
I assume that this would include port forwarding on the router which is not a problem, but I truly have no clue where to start. I have a very basic install of Cent-OS 5.3 (no X and just Base a few admin and dev tools) and just installed the latest RPM of bind (9.3.x).
I got two issues with my wifi usb adapter:
1) it cannot see any networks around
2) i cannot setup it in master mode to use my PC as a router

I was able to connect to a laptop somehow (the laptop could see other networks and the adapter's PC-to-PC network). I'd like to make it work as a router, i.e. share my internet connection (eth0) via wlan0. Here is what i have:

I'm setting up a home network and trying to set up a Ubuntu Server (10.04) as a samba file server and a web server.I installed Ubuntu 10.04 Server and the automatic network configuration during installation failed.

I'm trying to get my SSH server I set up on my home box working from behind a router. A 2wire 2700HG-B gateway, in fact. Now, I know my server is working fine, because I can get into it via loopback, anywhere inside the LAN from another machine, OR if I go into the router's config and enable DMZ for the machine. However, I don't like having DMZ on all the time because of the kludge-ness of it, and the security issue of the complete absence of a hardware firewall.If I try to port forward and access it from outside the LAN using the external IP (or my DynDNS, because it's dynamic), it just times out. I have a nonstandard port (45) for the listen port of the server, to keep away hack attempts if I were using the standard 22. I used this to see if the port was open, and it said it was. But, I tried the trick of telnetting the IP with that port, and it also timed out, instead of printing stuff about OpenSSH.
Attached is a screenie of my router's firewall page, so you all can look at it and see if I'm an idiot and doing it wrong. You might notice uTorrent there, it's because this machine is a dual-boot with 7, and the router doesn't differentiate the OS's. Also the SSH @ 46 port is for the Windows side, with freeSSHd. I changed the port on that one so the client I have can distinguish them, so it can run a reachability test.
post the "perfect" tutorial for setting up a router and firewall for Ubuntu 10.10 Server 64-bit? I'm kind of a n00b when it comes to Linux, so I get really confused with some things, I have seen things on the ubuntu wiki about this... but it really confuses me =
I'm trying to setup my ubuntu sys as a router and firewall... Internet -> Ubuntu (Router) -> Switch (no DHCP on it) -> Computers I've already setup bind and dhcp3 and got those working perfectly... I've also setup Squid3 and Dansguardian for content filtering (blocking ads and such) and got them working too... I want to set it all up to be transparent, and allow the system itself to function as a powerful firewall router, giving absolutely NO issues to client computers connected, and no speed reduction at all.... I want to setup the firewall to allow all outgoing connections, but block everything incoming (stealth the network)... Forcing all http/s traffic to pass through dansguardian, then to squid...
But am very confused on how to pull this off... The system is running Ubuntu 10.10 Server 64-bit, with 4 GB of RAM, 320 GB SSD, and two 1Gb NIC cards... Sorry if I'm not very clear, I do speak english perfectly, but just kinda new to the "Linux world", I was using SONICWALL but that's getting a little too costly to my network and wanna do a free alternative... Something completely CUSTOM, not using some network security distro.
I want to do is setup a gateway(or router, idk what Ubuntu refers to it as.). So my set up would be Modem>Server>Switch>Router. I know that I need to set up it up as a DHCP server as well. I would also like to setup it up as a firewall too. I already have two Gbit cards that are already configured. So how do I do this? I already tried one tutorial, but it was old and was for Debian. I also installed ebox, but I couldnt figure that out either.

Using Ubuntu 10.04 LTS.
I have an intranet server behind a NAT router. Very standard linksys router home setup. The server has a static IP. I used port forwarding in the router to use SSH and log into the server remotely - it works OK.
I want no one outside my home network to access any webpages on the server unless they're authenticated.. I know I could port forward like with ssh but with http port 80 and then see webpages , but again this would open it up to anyone with my cable modem's IP - wouldn't it?
I need a secure way like SSH that requires a password before anyone could access port 80 and http from the server from a remote network.
How do I do this? And on the local network people can get served pages normally as usual. Just remote would need authentication. Must be commonly done(?)

A server is acting as a router between two networks. If the load increases what happens, to the speed of network? whether the network speed will be reduced or it will sustain the same speed (Ex: 100MBps).
