Socket issue

[bukkan]

Hi,
i have 2 computers (one laptop and another pc) connected via a dlink modem (GLB 802T) and a netgear router (WGR614v10).

I am developing an winform server and a winform/silverlight client application. the same is working fine in localhost or when i am trying to connect within network (10.0.0.X). but when i am trying to assign a public ip (dynamic, 59.93.xx.xx) the same is throwing an error - "no connection could be made because the target machine actively refused it"

a similar server/clinet app as described here in the below mentioned project too fails to connect.

i have forwarded the ports, made firewall exceptions/disabled firewall, but nothing seems to work.

can anybody point me the right direction.

thanking in advance...

It depends on the router, but if you are trying to perform a local loopback, most home routers will not allow it. You would also need to map the inbound port to the server machine (which it looks like you are attempting to do). You might need to change the SLPolicy category to Servers for the communications to get back inside your firewall.

I removed the router an tried to make an connection (in the same pc) using a public ip address using the modem only. but that too failed

got my killer app ready (working fine in local address), but .....
