[Openswan Users] Openswan + IPTables SNAT both side traffic, is possible?

[Claudio Prono]

Hello all,

I use OpenSwan with a special IPTables SNAT rule because to the other
side they have the same subnet IP addresses. So i have inserted a rule
like this:

iptables -t nat -A POSTROUTING -s 10.10.0.4 -d 192.168.0.22 -j SNAT
--to-source 11.10.0.4

With this rule the client present itself as 11.10.0.4 and all works
without problems, when the client tryies to access the IP 192.168.0.22.
But it doesn't work if is the 192.168.0.22 trying to contact the
11.10.0.4. I have tried some different rules, to do a reverse nat for
the traffic from 192.168.0.2 to 11.10.0.4 natted to 10.10.0.4, but
without any success. Any hint about it?

If you need more configuration about OpenSwan, contact me.

Cordially,

Claudio Prono.
