Hello Agri,
This doesn't seem to difficult--are you telling us the whole story? :)
: i have private network let it be 192.168.0.0/24
: and and two external networks,
: let it be 10.1.1.0/24 and 10.2.2.0/24
: ip addresses of my linux box is
: 192.168.0.1
: 10.1.1.1
: 10.2.2.1
:
: i want to masquarade all private network addresses through 10.1.1.1 but
: also if destination is not at 10.1.1.0/24 want to route masquaraded
: packets through gateway 10.2.2.2
routing + masquerading:
ip route change default via 10.2.2.2 src 10.1.1.1
iptables -t nat -A POSTROUTING \
-s 192.168.0.0/24 ! -d 10.1.1.0/24 -j MASQUERADE
or, better, just use SNAT --to-source:
iptables -t nat -A POSTROUTING \
-s 192.168.0.0/24 ! -d 10.1.1.0/24 -j SNAT --to-source 10.1.1.1
Let us know if this doesn't do it.
-Martin
