Ok so let me explain, i bought WRT54G and successfully installed DD-WRT v24-sp1 (07/26/08) mini-special - build 9994. That's all ok no problems with it all normal functioning. And just to add (i don't need wireless, wireless is turned off always)

What i want:
ISP's router (TG782) from it's INTERNET port(out) cable "which was before in my pc" is connected to WRT54G's INTERNET port and then from WRT54G LAN port 1 to my pc.

The problem: How do i connect and setup all? I have tried many times on many different ways but cant get it to work IF THE CABLE FROM TG782 IS CONNECTED TO WRT54G ON INTERNET PORT.

If i connect the TG782 to Lan port 1 on WRT54G and my pc to lan port 2 then all works fine after i setup gateway and all. But i want to connect TG782 to Internet port of WRT54G because i need "Access Restrictions" and this only goes through WAN right? please correct me if i am wrong.

What i have tried:
This is how i have tried to setup all. The TG782 router ip is
And WRT54G ip is so in WRT54G control panel i have setup like this:

----WAN Connection Type----
Connection Type: Automatic Configuration - DHCP
STP: Disabled
----Router IP----
Local IP Address:
Subnet Mask:
Gateway: (the TG782)
----Network Address Server Settings (DHCP)----
DHCP Type: DHCP Server
Start IP Address:
Maximum DHCP Users: 6

And this wont work i probably miss something more, if anyone can help i would be thankfull. Also i have to note that i have tried to set my network adapter on pc to use the gateway of WRT54G and ip

In short: i cant get it to work normal only as a switch!

Thanks for any help!


Here is an image which maybe can help:

Make the subnet between the TG782 and the WRT54G different than what's on the LAN side of the WRT54G.

Ie: If the DHCP server on the TG is handing out 192.168.1.X (, then have the DHCP server on the WRT hand out something like 192.168.2.X (

If the network (segments) are the same on both sides of the WRT router it may be confused on how to route traffic, as it's expecting to find a different network on each side.
