In news:edHD6TE5FHA.3908@tk2msftngp13.phx.gbl,
Emyeu <cmchong20@yahoo.com> made this post, which I then commented about
below:
| Quote: | On the firewall, i have open tcp port 53 for external to internal. it
still failed when telnet from external.
Is there any setting to be performed on DNS sever?

Is it a NAT device? If so, did you port remap it to the DNS server internal
IP address? UDP needs to be open too.

the external dns server (with public ip) is in the same subnet, private ip,
as the firewall.On the firewall,both TCP 53 and UDP 53 are open.
