I have a ASA5510 ASA v7.0.8 in routed firewall mode. It is setup as the internal router and default gateway.
I was asked to set up a wireless router, I chose a D-Link DIR-815.
I have it all set up but I cannot get any name resolution.
The firewall is blocking traffic that is all internal. To clarify, it is only blocking the DNS traffic from the D-Link wireless router, the rest of the network operates just fine.
the message in the ASA log is like the following:
Deny inbound UDP from 192.168.1.246/xxxx to 192.168.1.10/53 due to DNS Query.
.246 being the “WAN” port my wireless router and .10 being my DNS server.
I tried adding an ACL “access-list dns extended permit udp any eq 53 any” but this didn’t help.
