Hi All,
I am trying to configure a network with the following scenario:
Pc --> Switch --> Router --> T1 Data Connection
I have the data connection working with NAT / PAT to my client PC's within the network. I can reach the internal (10.1.x.x) / external network via ping. However, I cannot resolve internet addresses from the client PC's. I can resolve internet addresses from my router (ie ping www.google.com returns the correct info). From what I undertand, I should put the router's address as the DNS Primary server on the PC's network config, then have the router's serial address (internet facing connection) contain an ACL that allows DNS udp traffic?
Can you verify why the following ACL is not working for my connection?
!
interface Serial0/0/1:0
ip address 12.X.X.X 255.255.255.X
ip nat outside
ip virtual-reassembly
encapsulation ppp
crypto map CM
service-policy output VOIP
!
ip nat inside source route-map RMAP_1 interface Serial0/0/1:0 overload
access-list 101 permit ip 10.1.0.0 0.0.255.255 any
access-list 101 permit udp any any eq domain
access-list 101 permit udp any eq domain any
route-map RMAP_1 permit 1
match ip address 101
I appreciate any assistance with the topic.

Hi,
You will need to use your service provider's DNS server addresses on your PC. Your router isn't providing any translation services.
Hope that helps..

Hi,
Thank you for the reply. I tried inputting the provider's DNS settings on the client PC and I'm still not able to get internet html pages on the computer. The addresses are not resolving to IP's. I can ping external IP addresses, but cannot ping web addresses such as google.com. Is there another access list that I am missing?
Thanks again for your help.

If the router can ping by name, and is runnign a recent IOS, configure:
ip domain-lookup
ip dns server
and use router's address as DNS on the PCs.
Hope this helps, please rate post if it does!
