ISDN 803 CONNECTED TO A DHCP SERVER

[avionics]

I have a ISDN 803 router and woud like to know how the dns server ip would be affected if i add a dhcp server(2000 server) and will the router be accessable to give the users access of the isdn lines. I other words what is a generic ip set i can assign to my network to make everything communicate.

Hello,

as long as your DHCP address pool matches the source list of your NAT statement, you should be fine, since everything your DHCP server dishes out would be translated to the IP address assigned to your ISDN interface. Let´s say your DHCP address pool is 192.168.1.0/24. So all your users would get addresses from this address space. Your NAT statement would look like this:

ip nat inside source list 1 interface bri 0 overload

and the (access) list 1 mentioned in this statement would be:

access-list 1 permit 192.168.1.0 0.0.0.255

HTH,

Georg
