837 dialin - getting assigned DNS addresses - TWICE!

Hi all (again),

Can anyone spot what is wrong with this configuration (see below) ? When I establish a pptp connection I get assigned my DNS addresses as duplicates! This si the output from "ipconfig /all":

PPP adapter Jim:

Connection-specific DNS Suffix . : Description . . . . . . . . . . . : WAN (PPP/SLIP) Interface Physical Address. . . . . . . . . : 00-53-45-00-00-00 DHCP Enabled. . . . . . . . . . . : No IP Address. . . . . . . . . . . . : 192.168.1.191 Subnet Mask . . . . . . . . . . . : 255.255.255.255 Default Gateway . . . . . . . . . : DNS Servers . . . . . . . . . . . : 212.104.130.9 212.104.130.65 212.104.130.9 212.104.130.65

Why are 212.104.130.9 and 212.104.130.65 listed twice?

config below.

Many thanks,

Jim

I cannot tell why you are getting the double DNS entries but I would suggest that your DIAL-IN pool use a different IP address range than your LAN interface. For example use 172.16.1.1 172.16.1.5

Many thanks merv, I've now changed that you follow your suggestion. Stranegly, the duplicates aren't appearing anymore.

Sorry to prey on your kindness, but have you any ideas re: my other open questions in this group, from the last couple of days?

Cheers,

Jim
