Hi, sorry for these 3 simple questions I'm sure.
1.) I have a Cisco 837 for my home ADSL, it all works but I had to manually add the DNS servers from my ISP into the DHCP pool, is this normal or should it be automatic?
2.) What command can I use to find out my external IP?
3.) What command can I use to show what ADSL line speed I'm getting?
Correct, it won't import dhcp server in dhcp, so far no config is possible to do so.
Either live with the server statically dns, or configiure the router as dns server:
"ip dns server"
"ip domain lookup"
set router's address in dhcp, and will do dns in there.
Other Qs is show ip interface brief" and "show dsl interface".
Hope this helps, please rate post if it does!
