I can setup remote access to a pc behind a single router/firewall by using NAT and Port Forwarding, simples!

But there is a customer that shares an internet connection with another office, and they are behind a second router firewall. I drawed a picture with my crayons but I can't attach it because I'm a new account on SF. see it here: http://i.imgur.com/b3FDx.png

So how would I setup remote access to the pc that is beind the second firewall?

It must be something about static routes, i.e.

if I hit the wan ip on port 4905 I want it to forward it to 10.0.0.30 by going through 192.168.1.10

so a route statement like for all requests to 10.0.0.30, use 192.168.1.10 ?

and ass u me router 2 has a static gateway ip of 192.168.1.10

and need a standard NAT on router 2 to point port 4905 to 10.0.0.30

is this the right way, any tips?

both routers are netgear consumer equipment.

thanks
