IPSec tunnel with Public IP interesting traffic and NAT

[merlinios]

Hello all,

I'am very confused about a configuration i have to made. We have 2 sites . In site A  Pfsense with 1 Public IP in wan interface and behind pfsense a server with a private IP with 1:1 NAT that takes another public IP . Remote Site has a cisco router with a public ip and a private subnet from behind.

So , site2 has a prerequisite that the interesting traffic must be a public ip which in our case is the public if of the server behind the SiteA pfsense and also dnat to that ip some ports.

Any ideas how i can do such a thing ?  pfsense is version 2.2.4

Thanks a lot
