851W ISP DHCP problem.

Unanswered Question
Aug 11th, 2008

Hello all,


I currently have a 851w at home and recently I wanted to use dynamic dns. So I configured everything for ddns and I couldn't get it to work. After some digging I discovered my ISP was setting my routers hostname as "newpc". Is there anyway to overwrite this to the hostname I want. The hostname of my router doesn't change to "newpc" but when it updates dynamic dns the router appends "newpc" instead of my hostname to the domain name. Here is the dhcp debug (I bolded the line where it sets my hostname) and I attached my config. Thanks for the help.
