Hi All;

Please forgive me if I overlooked a similarly posted topic. I'm having trouble with remote users not able to resolve IP addresses from hostnames through PPP dial.

I've tried tinkering with Windows DUN, to no avail. Is it possible to append the DNS settings to the PPP sessions? If so, please enlighten me. Thanks a million!

Regards,

Marcos

During IPCP phase of PPP negotiations, dialin server can send ip address of Primary and Secondary DNS server to dialin clients, DUN. Once the DNS ip addresses are assigned/negotiated by dialin client, it will send all the querries to thise DNS servers.

You need to configure DNS servers ip addresses using following global command

async-bootp dns-server 172.16.224.100 172.16.224.101

Where .100 is primary and 101 is secondary DNS servers. You can visit fillowing link for more on sample config and troubleshooting
