Hi folks, here is my issue:
I am atempting to set up a 3745 running 12.3.6 Advancd Enterprise with a NM-2CE1T1-PRI and 30 Digital modems as a NAS to support a number of individual users over Async dial up.
I can connect to the NAS, and use RADIUS to complete authentication, but the DHCP I have set up on the router doesn't appear to work. I can use an address pool to hand out IP addresses, but I want to hand out Default Gateways and Subnet masks as well, so I figure that DHCP is the only way to go.
I ran a debug on DHCP (wouldn't you know it I don't have the output - I'll post it later if required) but all it said was it was unable to get NBNS Primary, DNS Secondary and NBNS Secondary.
Any advice will be gratefully recieved.

See if this sheds some light on your problem :
Using the Cisco IOS DHCP Server on Access Servers:

However, I am wondering why would you like to supply default gateway and mask to a dialup client? As you know default gateway on a point-to-point link is not meaningful and hence its the client's own IP address itself while mask (that gets handed out via DHCP rather than IPCP) is only useful to give the peer a block of IP addresses that it can assign to CPE devices (if any) behind it on its network.

Thanks ~Zulfi - your straightening me out on point-to-point links solved my issues...
cheers
