General :: Installing Firewall / Gateway Into Linksys Router To Protect Windows?
Apr 1, 2010
story is my brother is a dindows lover (gamer) and hes been gettin attacked by virus's,etc cause he runs his Vista setup with no firewall or antivirus
He says the firewall,etc slows down the PC too much for gaming He doesnt want to use Linux as his games wont play on Linux as on dindows
He wants to know if you can install a Linux firewall/gateway or whatever into his Linksys WRT54GC router and thus protect his PC without using a firewall or av in it.
EDIT: precisely; he has a Linksys wireless-G connected to a always-on Verizon Westel 6100G modem so its a wired connection, not wireless

So what 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.

I have been happily running the (always latest) version of PolarCloud's Tomato software on my LinkSys WRT54G for about 2 years now. I am looking for a way to setup a Proxy Server on my Tomato-based router to use from a remote machine somewhere in the web cloud.The reason for wanting to set this up follows. I normally run Squid on a Ubuntu 8.04 box, which I use while I am away from my LAN at home to browse the net (I like to keep things between me and my ISP, as much as possible . I rely on my proxy server on a daily basis. The way it works is I SSH into my Ubuntu box, and forward squid ports. I then point my browser to the proxy on my box. For various reason, however, I would like to set it up so that I can also do this via my router. So, I would like to be able to ssh to my router (I can already do this), forward the proxy ports, and surf the nets happily via my router at home. I am happy to use existing solutions (if possible), such as privoxy or squid, and am also open to setting up a custom-based solution, as may be necessary.

I've set up a Lan-to-Lan (routed) OpenVPN tunnel. For redundancy I want to set up a second VPN tunnel on a fallback gateway/firewall on the client side. Currently, both sides (server/client) know how to route packets across each others physical LAN. So no NAT is used. When the primary gateway (fw1) is connected to the VPN server all traffic runs via the fw1 tunnel. Than when the secondary gateway (fw2) connects to the VPN server and fw1 is still connected all traffic for fw1 will be delivered to fw2 and effectively destroying traffic intended for fw1. This is of course no problem if I first shutdown (fence) fw1, than set up fw2 to use the gateway IP address from fw1 and set up the VPN tunnel to the VPN server. Effectively replacing fw1 with fw2 on the client side.
However, I can't seem to find a decent howto.
I am also exploring the possibility to let both tunnels active and let OpenVPN (or another tool) decide how to route packets back and forth the different LANs. A virtual IP between two gateway's both running a VPN or something similar. This would be the preferred method of course. However, I don't know how to tackle this one but I'm pretty sure there are people out there who are happy to share their 2 cents.

Our firewall (debian) currently has 4 public ip addresses (eth0 1.2.3.4, eth0:0 1.2.3.5, eth0:1 1.2.3.8, eth0:2 1.2.3.9) and 3 internal subnets (eth1 10.1.x.x, eth1:0 10.2.x.x, eth2 10.7.x.x). We are experiencing the following two problems which I believe have the same root cause. 1) The firewall cannot access beyond the isp gateway (1.2.3.1). 2) From externally, we can ping eth0 with no trouble, however, pinging the eth0:0, eth0:1 and eth0:2 interfaces have results similar to the following:
Code:
PING 1.2.3.8 (1.2.3.8) 56(84) bytes of data.
64 bytes from 1.2.3.8: icmp_seq=2 ttl=57 time=59.0 ms
64 bytes from 1.2.3.8: icmp_seq=2 ttl=57 time=63.0 ms (DUP!)
64 bytes from 1.2.3.8: icmp_seq=13 ttl=57 time=59.3 ms
64 bytes from 1.2.3.8: icmp_seq=13 ttl=57 time=63.0 ms (DUP!)
64 bytes from 1.2.3.8: icmp_seq=24 ttl=57 time=62.0 ms
64 bytes from 1.2.3.8: icmp_seq=24 ttl=57 time=65.6 ms (DUP!)
I get the feeling that I'm missing something obvious, especially since all traffic on the internal subnets can access externally as normal.

I got 2 servers, each on different locations (server 1 and server 2). I want all traffic on server1 included web browsing, applications etc., be always going through server2, like a gateway. I want the traffic to be encrypted (maybe use VPN?) So if I browse, or any logs pick up ip adresses from applications used by server1, I want it to display the IP address from server2 (Might be the wrong way to say it).
I always wants server2 to act as an firewall and logserver that logs all the traffic. I was thinking about using Snort for IPS/IDS solutions and OpenVPN for the traffic, but what can I use as a firewall? Most firewalls I find on google has its own OS/Distribution. Maybe Squid for logs? But squid does not support much protocols. Distribution on both servers are updated Debian/Ubuntu based.

I have been using the B version for many years, just got the G version for a B-day gift. I run OpenSuSE 11.3 and XP on one computer but I have several (3) wireless laptops in my house plus a xbox wireless. I also have 2 other ethernet computers connected to the B version. Can someone provide me with some links/info on how-to. When I did a Google search all I came up with is firmware upgrade...which I've done for the B version. Is it as easy as taking out the old...configuring the new?

I set up my linksys router for PPPoE and username, however, if the compter goes idle after a while, I have to go back into the configuration page, save settings and everything is ok. I would like to keep the connection alive 24/7. There are two settings:
time to live (max idle time)
redial
Max idle time is now set at 10 minutes. The redial is grayed out. Are these the settings I should be concerned about?

My Ubuntu 9.10 is intalled on a partition on my computer HDD. The other partition OS is Windows XP. My Windows uses McAfee as the antiviral program. Granted that linux is at a much less risk for viruses, some still apparently can slide through on incoming emails from Windows computers.
1) Will my Windows partition McAfee protect the entire computer?
2) If not, suggestions for an anti-viral program?

I am dual booting XP and Ubuntu 10.10 64bit on a Dell Latitude E6410 and I have a Linksys WRT120N router connected to my Modem.
So the weird thing is, under XP I can use the internet while connected to my router. Under Ubuntu I can't use the internet while connected to my router. But I can use the internet in Ubuntu if I connect to my neighbor's router called "linksys". So something happens when I connect to my router that makes Ubuntu not able to access the internet. But if I'm connected to my Neighbors router or if I use XP while connected to my router I can use the internet.
I have been using Ubuntu for about a year, so I'm getting better but still a noob. I've tried to figure out what's going on by looking at other forums and posts and trying to see if anyone has solved this. So far I've had no luck. This is also the first of many problem I have encountered that I have been unable to solve using online posts, and is the first problem that I have had to resorted to creating a post to try and fix.

Server details:
OS: Linux RedHat
DHCP: Static IP set to 192.168.1.101
sshd_config: Enabled for port 22 for ssh
Connected through wire to the Linksys router
Router:
Type: Linksys BEFW11S4
Port forwarding enabled for port 22 to IP 192.168.1.101
Client:
Windows 7
Interface: PuTTy
Host: 192.168.1.101 on port 22 through SSH
This always gives an error "connection timed out". SSH directly on the local Linux works fine.. Seems basic but had been struggling over this for past 3 hours to no avail so thought of posting it to the experts.

I am running Fedora 13 and I have a linksys WRT54G wireless router [1,2]. I'm having a strange problem. I'm using a computer connected to the router via a wired connection. At intermittent moments the connection seems to stop. I can't even ping the router (192.168.1.1). However, if I make NetworkManager reconnect to eth0 the connection immediately comes back and I can ping the router and navigate to websites. If I wait a random amount of time the connection also seems to comes back on its own (without reconnecting via NetworkManager). Any idea if this is a hardware (router) problem or a software problem? This didn't happen a month ago.
P.S: I have already updated to the latest firmware (Ver.8.00.8).[URL]..

On this Ubuntu 8.04.4 LTS server, I want to log the messages from a Linksys router. So I made this change to "/etc/init.d/sysklogd" SYSLOGD="-r" Then in "/etc/syslog.conf" I added the following to the top of the file: Code: if $fromhost isequal 'Linksys' then /var/log/Linksys.log & ~
Then I rebooted the server. But there is no "/var/log/Linksys.log" file.

Okay, a few days ago I got a small job setting up a router for a neighbour of mine. He wanted me to set up a wireless network for him. The router he bought is a Linksys Wireless N-Router E1000. I set it up the passwords and everything. Only to find out that I couldn't connect at all to it. The main computer with a direct ethernet connection to the router was the only one that had internet. Everytime I attempt to connect wirelessly with any device, it will take extremely long time to connect, to the point where I will just quit connecting.(Example: 15 minutes of waiting, when the laptop is right next to the router)
Any ideas about what I am doing wrong here? As far as I can think of it might just be a faulty router, because the router will not implement any changes(like setting a password) I set on it. Only wired connections seem to work. the router is called a linksys wirless N-router E1000.

I have an Acer Aspire 1 Netbook - this is running UBUNTU- When I try to connect to my Linksys Router in wireless mode it asks for password - but doesnt accept. I can see the Linksys in network manager plus several other networks in the vicinity. My other wireless devices all connect O.K. to the Linksys, and accept my password.. I can hard wire by ethernet to the netbook. Just wireless is the problem

I have a linksys router in my basement and physical access is pretty much blocked by a stuck trap-door. I could try to shut off the main power switch, but I like to see that as a last resort. The problem I have is that I have an open (no encryption) wifi connection between my pc and linksys router, yet I cannot connect to it. Until a couple of days ago I could connect to it with my android handheld device, my linux laptop, and my windows desktop. All these devices are now unable to connect. I attached the wicd log from my linux laptop. How to gain access to my router again?
