Re: Internal PC/external Gateway

["Sadus ." <sadus@swiftbin.net>]

this is after your email my current setup.

iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to 10.2.2.1
iptables -t nat -A POSTROUTING -s 192.168.1.3  -j SNAT --to
192.168.0.141

and 
#!/bin/bash

IF1=eth0

#Provider 1
P1=10.2.2.1
#Provider 2
P2=192.168.0.173

ip route add default via $P2 table T2
ip rule add from 192.168.1.3 table T2
ip route flush cache

can't i keep it like that? or i have to set T1 too?
thanks.
