[Cerowrt-devel] vpn fw question

[Joel Wirāmu Pauling]

I.e Your topology looks like this :

[(Remote LAN) - VPN Client]---[INTERNET]---(Local LAN)[WAN][LAN][REMOTE-LAN])

Your Local LAN knows nothing about Remote LAN and Vice versa. There is
just a single Inteface/Client member that is a member of REMOTE-LAN.
So to get traffic from Local LAN to Remote LAN all Local-LAN traffic
needs to be masqueraded to that Single interface.
