Just tell your work station what you want IT to use. Do you know your ISPs name server? Try dig a www.google.com @ip-of-isp-ns If it works real quick, set that name server in resolv.conf and tell your local dhcp client to NOT overwrite resolv.conf -- alan dot mckinnon at gmail dot com

It's impossible (for me, at least) to get a mental picture of what's going on. Hidden in the middle of the dumbed-down doku, it says that the router must use the DynDNS service of some provider, e.g. URL 1 or URL 2. Details of how to use a particular service can be found on the corresponding web page., the sort of thing that makes me scream. And that's it. There is nothing there to say the address of the actual name server in use is secret, or how you actually find it. /rant mode Anyhow, it is surely not the router setup which is the problem - name lookup works fine under my Debian sarge system. allan -- Alan Mackenzie (Nuremberg, Germany).
Re: [gentoo-user] Network configuration: looking up URLs is very slow; how can I fix this?
As long as speedport.ip is 192.168.2.1, the routes are okay, and the resolv-file is okay aswell. It's most likely either DNS-cacheer, i.e. your own router, or the DNS-server your ISP is giving you beeing the bottleneck. You could go ahead and dig(1) both those servers and perhaps time(1) that. If you can find any logs in your router that would help aswell. -- Daniel.
