Hello, I would like to know if such configuration is possible.
LAN1 (192.168.10.0/24) <--> OpenBSD .99 <--> .254 Router IPx <--> Internet <--> IPy IPSec_GW (Vendor) <--> LAN2 (192.168.20.0/24) As you can see the OpenBSD 4.9 server sits on the LAN1 and has one physical interface. When it wants to access to the internet, its address 192.168.10.99 is natted in IPx and that's how the IPSec_GW(Vendor) sees the source packets. It's not really important now if other machines on LAN1 should ping machines on LAN2. I would like for now that the OpenBSD could ping machines on LAN2. I have search for examples on the internet for this particular case because the OpenBSD is behind a nat router. And I haven't found the proper way to do this. I don't even know if it's possible. I know some kind of nat-t should be used though. Does anyone have this configuration in place ? Thanks
