Hi all, I,ve just installed openwrt on a Lynksys WRT54G. It is attached to a  D-Link DFE-96Ds router which also has a Linux file server attached which I wand to keep on a seperate network. The D-LInk router is attached to a Caymen 3300 DSL modem. Before I installed  OpenWRT the LYnksys was set to 192.168.10.1 and was working fine. After the installation I could not Telnet into it so I held down the reset button for 30 seconds. I can now telnet into it at 192.168.1.1 but I can't ping anything outside the unit. Which files do I have to edit to change the units IP adress back to 192.168.10.1 Has anyone written a howto for changing settings in OpenWRT? Any advice or help would be very much appreciated.

Read the documentation and take a look at

root@Daniel:~# nvram get lan_ipaddr
192.168.2.1

I think you have to change it.

I've read the Docs and deleted  udhcpd.conf from /etc. I then copied it from /rom/etc and used vi to edit the ip to 192.168.10.1. Then  I rebooted the wrt. However when I opened udhcpd.conf it had reverted to 192.168.1.1 What am I doing wrong? Maybe it's just that Ive lost two nights sleep fighting with it and I'm too tired  to spot something simple.

Try to change the lan ip-address.

Do:

nvram set lan_ipaddr=192.168.10.1
nvram commit
nvram_commit(): start
nvram_commit(): end
reboot

Now you can telnet to the routers ip-address 192.168.10.1.

Thanks Duff. That helped me to understand what I'm doing a bit better. I can now telnet into the WRT and set IP etc. I have a static IP and I have setup pinholes in the Caymen DSL mdem to allow traffic over various ports for smpp, http, smtp, jabber and other services that I run on my main server. The Caymen modem handles DHCP. However it is not giving a lease to the WRTG. Any ideas or pointers you can offer? Regards Sean
