Bogdan,

I'm trying to use my iPhone from home to route via my PC (vpn). It's
more like this below ...
iPhone, wlan, home PC has private IP. I'm routing from my iPhone to my
PC to the office to get a trunk out.

iPhone - wlan - PC(home) OpenSIPs - VPN - PC(office) OpenSIPS - ISDN

I know very little about OpenSIPS now, but, again from I read, it
looks like nat_traversal can do the job ... I just need a working
sample if possible. I just can't find it on the net.

Thanks,
Jeff
