Hi guys,

I've tried a lot of stuff, but I still can't make a NAT inside the
tunnel with NETKEY.

Let me explain. I've a network A= I need to establish a
tunnel with a firewall that has the network B= Till here
everything is fine, the tunnel is up and running.

The problem is that the other firewall needs my network A to be
A=, because he already has a network on his

How can I make it work? :(

I tried to do SNAT, tried to add an extra IP with this network on a
LAN machine... I no even remember everything I did. So if anyone had
to do this before the help would be very appreciated.

Thank you very much!
