Local LAN sharing on ApexDC++ using Router

[coercion 0]

Hi, i am trying to use ApexDC++ using a wifi router for local LAN sharing. The problem is that when i connect the LAN cable on LAN port of the router i am able to connect to local HUB but at the same time unable to connect to internet. And when i connect the LAN cable on internet port of the router i get connected to the internet but unable to connect to local HUB for LAN sharing.

I have tried port forwarding also but of no use. The ip details provided for local LAN sharing is,

LAN IP - 192.168.100.3 - 192.168.100.xxx

Subnet mask - 255.255.255.000

Default gateway - 192.168.100.1

This is the configuration on the LAN port of my wifi router. Where as when i connect the LAN cable on the internet port of router, it takes the ip automatically from server (DHCP) which is not the same as ip detail provided for LAN sharing hence unable to connect to local HUB. If i try to configure the internet port of the router with above configuration i am unable to connect to local HUB as well as internet.

I want to connect to local HUB while connected to internet using a wifi router. I don't find any problem while connected directly. I have configured my computer's LAN card manually with the above configuration provided for LAN sharing & able to connect to internet as well through dial up connection. (connected directly without using a router).

Pls. help. i am unable to figure out the difference between the two (direct connection & while using a router)

Thanx in advance,
