Hi all,

does anyone knows how to get around a build-in limitation of iptables?

Which limitation?

...

What i want to do is something like: iptables -t nat -A POSTROUTING -p tcp -port 873 -j SNAT -o br1 --to-source 1.1.1.82

If you mean "option -port is missing", then

--match tcp --dport 873

See man iptables-extensions(8)

...

iptables -t nat -A POSTROUTING -p tcp -port 80 -j SNAT -o br1 --to-source 1.1.1.83

iptables -t nat -A POSTROUTING -p tcp -port 25 -j SNAT -o br1 --to-source 1.1.1.84 etc etc ......

So basically i want SOME traffic being SNAT-ed, but not all !!

specifically: my six ipv6-tunnels towards H.E. don't like to be natted, the all have their own specific IPv4-addres.

Ah, thanks This seems to work, this allows me to selectively do a SNAT. Insteaed of "snatting" everything, i can do it on specific services, i hope i can void interferrence with my tunnels. tnx. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
