I have an ADSL line that allows me for maximum of 4 concurrent users with external IP addreses. The IP addresses are not static (they change every 3-4days).
My current setup is as follows:
* A-link Roudrunner 44B Modem connected to the main line
* D-Link DI524 Router (port 1) connected to the modem
* This leaves me with 3 ports and Wireless for my other machines
What I wish to do is:
* Have all my machines with static IP addresses for LAN
* still have internet connection
I've tried enabling DHCP on the D-Dlink Router with LAN IP 192.168.0.1 and IP range from 192.168.0.100 - 192.168.0.199. Then gave my machine static IP 192.168.0.101, subnet 255.255.255.0 and gateway 192.168.0.1....obviously it didn't work. I've tried the above with both the modem being connected to the router via port1 and WAN port... but I have the same results. I also tried to do the same without the router (direct connection between the PC and modem) still got the same results. Could it be that what I am trying to do is not technically not possible due to my ISP setup to ensure no more than4 concurrent users limit is in place.

I have an valid account,and I used pppoe-setup to set the dial correctly.After the configuration,I typed "ifup ppp0",nothing wrong happens(no news is good news?).Then I typed "pppoe-status",it said I've connected to the internet . I opened firefox,updated my system through yum ,they all said I haven't connected to the network!!!I've formated my harddisk and reinstall my system,but the problem is still.

i have a leased line ( speed 2 MB ) which we use to connect to our mail server , oracle ERP etc.. we have a dhcp scope defined as 192.168.100.1-192.168.101.254. with a default gateway as 192.168.100.90 ( which is a cisco router ) we have a pix firewall ( 192.168.100.10 ).. now the gateway passed all the request to firewall..
we have an ADSL of 4 MB speed.. ip is 83.*.*.230 from ISP. i have a proxy server ( squid ) eth0 is connected to ISP (83.*.*.230).. eth1 to LAN ( 192.168.100.79 ) now the problem is when i put default gateway to eth1 ie 192.168.100.90 the squid connects to internet via leased line.. if i leave the default gateway field empty on eth1 , the squid connects to internet via ADSL ( which i want ) but the problem is no one on the lan cant ping the squid server ( no connectivity to internet for the whole LAN ) how can i solve this problem? i want squid to connect to internet with ADSL, but if i put gateway on eth1 ie LAN squid goes through leased line which i dont want to happen.

I have 2 pcs at home. I dont have a switch so I can connect only one PC at a time to my adsl router/modem for internet access. In the past I had successfully connected the two PCs (NIC to NIC) to each other using the same ethernet cable which was supplied with my dlink adsl modem.
Recently the motherboard of on of my PC went bad so I replaced it with a new one. The problem is when I connect the two using the same Ethernet cable they won't connect. The lights on the Ethernet port won't light up. I can still connect both of them to the adsl router (NIC to Router) (one at a time).

I've set up a permanent DHCP lease for my MAC address. I did this hoping to resolve the fact that I share my Internet ADSL connection with my wife and my daughter (the latter a great bandwidth hog)!

I have a pppoe adsl connection. When I disconnect and try to reconnect, network-manager keeps asking for my password. I type it again and again with no success. When I reboot, it works again. On ubuntu, I use pppoeconf and it works well. So on Fedora I made a connection with pppoe-setup but neither ifup nor
Code:
pppoe-connect
commands work. When I type
Code:
pppoe-connect
, it says
Code:
/usr/sbin/adsl-start: line 217: 13409 Terminated $CONNECT
"$@" > /dev/null 2>&1
. When I type
Ifup ppp0 doesn't work either. However, with exactly the same settings, ubuntu connects to the internet.

I just set up a linux server which is acting as an internet gateway. For specific reasons, clients first make a vpn connection trough the internet to the linux server.
CLIENT ---->Internet----->Linux VPN Server ------> Internet
On the linux server iptables is configured for NAT. The problem is that the internet speed becomes slower than expected. I used windows and RAAS and the speed was pretty good. The server has only 1 NIC(eth0) and an alias interface is added to eth0. The alias is eth:0 with ip address 192.168.0.253
iptables config is as follows:
iptables -P INPUT ACCEPT
iptables -F INPUT
iptables -P OUTPUT ACCEPT
iptables -F OUTPUT
iptables -P FORWARD DROP
iptables -F FORWARD
iptables -t nat -F
iptables -A FORWARD -d 192.168.0.0/24 -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A FORWARD -s 192.168.0.0/24 -j ACCEPT
iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -j SNAT --to MY_VALID_IP

I have installed fedora 11 64 bit on a new computer. I have no problems accessing the computers on my local network, but can not get past the gateway. The gateway is running windows XP with IP address 192.168.0.1 and is named "internet". When I boot the new computer in windows, there is no problem. Here is the output of some commands I saw in other posts with similar problems:
$ /sbin/ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:24:8C:7F:10:0C
inet addr:192.168.0.245 Bcast:192.168.0.255 Mask:255.255.255.0
inet6 addr: fe80::224:8cff:fe7f:100c/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

Whenever i used to setup a new connection in Windows it would just ask me User name and password here i need to fill up something called as "Gateway" !? The connection won't be accepted unless i fill up something in there... So, what do i put in there? I'm on a LAN of 3 computers connected with a router.The router takes one wire as input from the modem(cable).

Previously had 2 Ubuntu computers setup Computer A (192.168.1.101) <=> Computer B (192.168.1.100) -> Internet Computer B was the gateway, and it is dual boot, one drive Ubuntu, one drive XP. I'm using XP as the gateway now, but Computer A is extremely slow, virtually nothing getting through.
Have checked sysytem logs, verified /etc/hosts file, and all the network side of things. Can ping either IP adddresses from either computer. On the XP side, have modified hosts and lmhosts, and the XP computer has very fast internet connection.
Did have Commodo firewall running on the XP, disabled that, and checked that no Windooze firewall was running. Have restarted the network on both computers a number of times. Can't figure out what the problem is. It's obviously on the XP side, as when I booted to Ubuntu (previously) on Computer B, the gateway worked just fine. Have checked the whole tcp/ip side of things on XP; seems to be okay.

I have 1 root-server with 2 NICs, both having their own internet IP addresses:
Code: eth0 = 8x.x.x.183
eth2 = 8x.x.x.205 We only have one gateway on that network:
Code: gateway = 8x.x.x.1 We want to use eth2 for postfix + http, and eth0 for all the other stuff.
How can this be setup ? With route / ip route / iptables ?

Since I have a new internetaccount, 2 days ago, I have a problem on my server [Fedora Core 8]. I use it as a router.
eth0 is for the internet.
eth1 is for my LAN.
But since my new internetaccount my server uses eth1 for the internet. This is a line from my syslog:
Code:
NetworkManager: <info> Policy set 'System eth1' (eth1) as default for routing and DNS. I killed the NetworkManager daemon and now it works but this must not be the way to do it? Where do I tell my server that I use eth0 for routing and DNS?

192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0

This might well be user error, but I can't get my dual homed server to gateway.
There are two NICs code...
It was working, until I was messing around with the patch cables and managed to get them swapped over. I've corrected them now but it no longer seems to pass packets between interfaces. I noticed because squid (transparently proxying) stopped working, other stuff on the box (postfix, dovecot, getmail, dnsmasq) is working fine, the internal NIC is visible from the internal network, the external NIC can access the 'net.
I've rebooted (more than once) but the problem persists, any network gurus spot anything obviously wrong?

I have 17 system (sys1,sys2,sys3.....sys17) in my office, and i am willing to setup a dedicated system to act as a firewall for that i have selected sys1 with two NIC(eth0 for local network and eth1 for internet) and i have configured to access internet in my office for that i have opened a wellknown port 80.but my clients are not accessing the internet..
and please check my sample IP configuration !!!
interface : eth1 (ISP IP)just for example
IP :192.168.0.2
gateway:192.168.0.1
dns:202.56.230.5
dns:202.56.230.6
Interface : eth0 (my local lan )
192.168.1.1
255.255.255.0
IP address of xp clients ranges form 192.168.1.2 to 192.168.1.16 with default 255.255.255.0
my question is that which gateway address and dns i have to give to my clients for accessing internet ?...

I am wanting a computer with an external dialup modem (ppp0 modem through a com port /dev/ttys1) to act as a gateway to the internet, forwarding internet traffic through ethernet (eth0 is set to static 192.168.2.2) to a router (the router is 192.168.2.1) where it will be broadcast to other wireless computers like my laptop (192.168.2.3). I've had this setup until recently when the gateway computer (the one with the modem) died. Now I'm replacing that machine with another box and an install of Ubuntu 10.10 but so far things aren't working for me.
Success so far:I have dialup access working on the new box. Took me a while to work out the configuration for getting dialup working, though the IP address is Dynamic (or it won't stay connected), "Check carrier line" is off, and "Ignore Terminal Strings (stupid mode)" is on in order to successfully connect and stay connected to my ISP. I also had to make my normal (non-root) user "lancer" a member of the "pid" group (the reboot) in order to use gnome-ppp as non-root. The laptop (192.168.2.3) is successfully connecting to the router (192.168.2.1) as I can see the router configuration page when I type http://192.168.2.1 into the laptop's web browser. This setup is unchanged from how I had it before when this was previously working and I don't want to change how the router itself is set up. What I want is to know what to fix in the new box in order to get it connected to the router (through ethernet) and bridging the internet through.
My problem is that whenever I plug in the eth0 from the gateway (192.168.2.2) to the router (192.168.2.1), Ubuntu's automatic plug-me-in network detection kicks in and I find my dialup no longer working through some kind of IP conflict (at least that's what I think it is). Maybe I don't have the "gateway" correctly assigned? (in the gateway computer for the ethernet connection, I had it pointing to itself as I don't know what to put for "gateway IP" as that is automatic So, just to check my connection, here I am pinging google (from the gateway computer which has the dialup modem) once a dialup connection has been made.
Code:
lancer@lancer-desktop:~$ ping www.google.com
PING www.l.google.com (74.125.237.17) 56(84) bytes of data.
64 bytes from 74.125.237.17: icmp_req=1 ttl=55 time=179 ms
64 bytes from 74.125.237.17: icmp_req=2 ttl=55 time=176 ms
64 bytes from 74.125.237.17: icmp_req=3 ttl=55 time=158 ms
[Code]...
What do I need to do in order to make Ubuntu of my gateway computer stay connected to my dialup but also simultaneously share an ethernet LAN to my wireless router and feed traffic to the other computers from there? I have googled this but some of the most promising instruction (e.g. http://www.ubuntugeek.com/sharing-in...in-ubuntu.html) call for packages like dnsmasq or ipmasq which seem defunct now in Ubuntu 10.10. Other pages seem to suggest dual-networks "can't be done" in Ubuntu [URL].. (what!?! I had it before my other gateway died)

I have an adsl modem acting as a bridge to my router my setup was working well for more than year now , but then the internet went slow . I set the modem back to PPPoE the problem was with the DNS server of the ISP so using ifup i set the dns t 8.8.8.8 (google) the connection is back , but when i set the modem back as a bridge slow internet does the router know that my dns is 8.8.8.8 or i should set the dns on the router ? I can't see an option to set the dns on the router ( i just enter my username and password from the isp to use PPPoE mode ) by the way i called the isp support they kept telling me to restart , i told them i did but i never restarted my pc . I'm sure if i tell them i'm running linux they will blame the os !

I'm having some difficulty with a internet/vpn setup. I have 3 network adapters on the server. 1x is used to connect it to the rest of the network 1x is used to provide internet (squid,dansguardian) 1x is used to connect to the vpn router
My interfaces file looks like this:
Code:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
[Code]...
The problem that I have is this: When the gateway on eth2 is set to 10.0.2.2 the VPN works 100% but there is no internet. When the gateway on eth2 is set to 192.168.0.6 there is internet but no VPN.
So what I want to do is, route all traffic that is supposed to go to 10.0.2.0/24 and 10.0.3.0/24 to eth2 and all internet traffic to eth0.
