Reaching internal computers through the external ipaddress inside private network

[Christopher Abrahamsson <toffe@xxxxxxxxxxx>]

Hi

I've been trying to solve this problem for quite some time now, but i 
can't really figure out how...
Here's my current setup:
                              _ my computer (10.0.0.3)
                             |
internet - iptables gateway -|- my server(web, mail etc) (10.0.0.2)
            (212.181.43.20)  |
                             |_ a bunch of other computers (10.0.0.x)


Basicly, what i want to do is to allow 10.0.0.3 to access my external ip 
through the internal network, so i can reach, say, the webserver at 
10.0.0.2 through 212.181.43.20:80.
I've tried some different iptablesconfigurations around, but it hasn't 
been leading anywhere near success.

Any ideas?

Thanks,
Christopher
