Stories similar to direct specific application traffic through gateway

On windows server 2008 I have 2 network cards both configured on the same network (i will explain the purpose in a second) NIC1: 10.35.1.98 Mask:255.255.0.0 Gateway: 10.35.1.254 NIC2: 10.35.1.99 Mask:255.255.0.0 Gateway: 10.35.1.254

What I am looking to do is route traffic to cisco VPN client's who get IP's in the range of 1.1.3.x via the 10.35.1.98 IP and all other traffic through the 10.35.1.99

I need the information regarding multiple interface card.

My Scenario is:

Eth0: 172.X.X.X / X.X.X.252 GW 172.X.X.105 Eth1: 192.168.X.X / X.X.X.0 GW 192.168.1.1

My Requirement is that:

Eth0 traffic out/in gateway 172.X.X.105 Eth1 traffic in/out gateway 192.168.1.1

Mean that traffic generate from eth0 forward to its own gate way, same as eth1.

I am using the elastix server (centos) with two

How do you calculate the data flown between a computer and the gateway computer. I have a Linux router/gateway running IP Tables which routes internet traffic in a LAN. I have individual users with IP/MAC Address mapped who access Interet through the gateway computer.

Windows is adding a route for a local address (10.0.0.90 - my fileserver) with a gateway of (10.0.0.138 - this is my gateway), the gateway only has a 100Mbs link so all of my fileserver bound traffic is being reduced to 100mbs, if I unplug the gateway it jumps back upto 1000mbs.

I am looking for some sort of routing trickery to set a specific source IP:

Local machine has two IPs;

Eth1: 192.168.0.1

Eth1:2 192.168.0.2

Default gateway is 192.168.0.254 via Eth1

Remote subnet is 10.0.0.0/24

Any traffic that is sent to 10.0.0.x host, I want to leave via Eth1:2 so that it has IP 192.168.0.2 when it is received by the remote hosts, or some how force 192.168.0.2 to be my sou

Hi everyone,I have been beating my head for the last few weeks on this problem, (although I have been taking the wrong approach, it seems).I need a gateway to direct web tra... [by zogthegreat]

I want to decide on application level which gateway to use to connect to the internet.

It can't be done by simple subnet rules, because it is really the application which should be able to decide which gateway to use.

E.g.

I have Ubuntu with 2 NIC:

eth1, ip 192.168.10.11, gateway 192.168.10.1 (set as default gw on Ubuntu)

eth2, ip 192.168.20.11, gateway 192.168.20.1 (this is set on a router, not in Ubuntu)

What I'd like to do is Route all port 119 tcp traffic to eth2 (192.168.20.11) and all other internet traffic to the eth1

I know I will need to use iptables but I wasn't able to put together a working solution

I run a web server (Debian Squeeze on a VPS), and the graphs provided by the hosting company show consistently that around twice as much traffic is incoming to the server compared to the outgoing traffic.
