"Connection failed" error

[GoogleCodeExporter]

What steps will reproduce the problem?
1. I can connect and control remotely my pc with my iphone when I am home,
through my home network. 
2. When I try to connect my home pc out of my home LAN (away from my
network), it generates the error: "Connection could not be made to host
[my.routers.ip.here] port 5900"
3. At home, I am behind my router which has static IP. At home using
ultraVNC on my comp and vnsea on my iphone is working smoothly as they're
on same Wi-Fi. When I am not home, I can not reach my pc remotely, that's all.

What version of the product are you using?
on my pc (XP) : UltraVNC Win32 Server 1.0.2 Release.

on my iphone (1.1.2);: Latest version of vnsea.

Please provide any additional information below.

I forwarded tcp and udp ports 5900 for my iphone and pc. I don't know what
I am missing but away from home, I can't do what I can when I'm home.

Any help is wellcome.
