Hi ,

I have a Cisco a "Cisco 7206VXR" and want to migrate to an ASR 1001 .

When doing the migration every Thing Working fine ( Routing , NAT ..) But the only issue i have is that dns is not working on y client.

I can Ping 8.8.8.8 or any public DNS but no Résolution.

Can some one help me with this issue.

I have heard this issue earlier as well, but not faced on ASR1002 or 1004. However one more post on the CSC has same qus but Unanswered.

Just for testing can u check with a ACL as below and apply on WAN interface.

!

ip access-list extended DNS-TEST

permit udp any any eq domain

permit udp any eq domain any
permit ip any any

!

int gix/x/x

ip access-group DNS-TEST in

ip access-group DNS-TEST out

!
