connecting pcs on different ip ranges

Hi guys.

this is a really long story and most of the history is irrelevant. basicaaly i help out a local charity that im a member off with it stuff.they have recently changed isp and have a new router which has come preconfigured. we do not have a the configuration page username and password altbough we are working on it as we have to set up port forwarding. the next issue is that we use static ips which is a system requirement.

the old router used ip 192.168.0.254. and the new one comes with an ip 192.168.1.254. this means that none of the pcs can see the router and dont have internet access.

once we have the roufer config page we will change the router ip to match the old one. i know i could go round and reconfigure all the ip addresses so they sit in the same range by simply changin every pcs ip and default gateway but that is a pain in the a. is there anyway than i can get the pcs to see each other without changing ips?

example of settings at minutr

New router
192.168.1.254

server
192.168.0.5
255.255.255.0
192.168.0.254

pc 1
192.168.0.11
255.255.255.0
192.168.0.254

thanks in advance

 

As a quick work around, can you get ISP support to remote manage into the router and change the router IP address from their side?

 

Sadly not. We have no direct relation with the ISP.

 

Have you tried to hack the router? try user/ passwords like root/admin, admin/admin, admin/password, admin/[blank], root/[blank].. what model is the new router?
Did you hook up a single computer, set it for DHCP and see if the router gives it an ip in the 192.168.1.x range?
Can you get to the web interface of the router?
Does it have a web interface?

 

Hi Foogoo,

Thanks for the reply. Its all sorted now. WE have re-configured the whole network. The problem was that the ISP had configured the New Router and applied a non-standard username and password... so we couldnt get on to the configuration page.

We did manage to get access to the page once the ISP provided the logon details but the local IP for the router cant be changed without doing some serious config work using telnet. I may have considered it on my own router but not on one that is the charities.

We have therefore reconfigured all the IP details on the rest of the network and reset all the port forwarding on the router. All sorted now.

Thanks
