Hi all,

I have a router given by my ISP when i applied for a broadband. Recently i bought a linksys WRT54G and i configured the ISP router as bridge mode and i can online without any problem. Following are my configuration:

Internet > ISP router (bridge) > WRT54G > PC

ISP router IP: 192.168.1.254

Linksys router IP: 192.168.1.1

I connect my network cable to the switch port behind the linksys router, i can ping and access web GUI of linksys router without any problem. The problem now is i can't acccess the web interface of the ISP router anymore. Do i need to configure something in order to access the web interface via the Linksys router?

Thanks.

Why would you need to connect to the web UI of your ISP router if its in bridge mode?? But yeah your going to have a problem with the IP ranges you have.. The linksys has a 192.168.1.x/24 network on its LAN side.. Why would it send any traffic out its wan interface to get to a 192.168.1.x/24 address??

If you want to be able to get to your isp routers UI on a 192.168.1.254 address -- change your linksys lan network to something different, say 192.168.2.x/24

The reason i want to connect to ISP router because that router can provide me some info about my ADSL line statistics like noise level which could cause slow internet performance.

So what you mean is to change the linksys router to different subnet? Could you explain why this could solve my problem?

Thanks!

Because then when you try to access a IP that is not on linksys lan network. It will have to use it wan interface to get there, the interface its default gateway is attached too. Your modem is directly connected to that interface! If you try and access a 192.168.1 network, the linksys is directly connected to that network on its LAN side.

For that matter your client will never even send the traffic to the linksys -- since its got an interface directly connected to that network as well. So it just will put the traffic on the wire.. Will not send it to its gateway (your router) Since it has a interface directly connected to that network!

Change your linksys lan network to something other than 192.168.1 and you will be fine.. I can access my modems web ui, thru my router but its IP is 192.168.100.1 Which is different than my local network of 192.168.1.0/24

Hi, i have tried, still can't work.

My ISP router IP is 192.168.2.1, mask 255.255.255.0

Linksys router IP: 192.168.1.1, mask 255.255.255.0

I still can't access 192.168.2.1

I have read in other forum, saying that if i configure PPOE as my internet connection, there is no way to access modem behind router, is that true?

Thanks
