DNS problem

[HuMPie]

Hi,

No you don't need to open broadcast traffic on your router( it's
definily has it's reason that it's closed, don't think this is the place
to tell why)
The only port's the DNS traffic's use is:
- UDP port 53 for resolving
- TCP port 53 for zone transfers

I don't know how you configured your VPN's but that's out of the scope
for this ML but normaly DNS traffic works fine if you allow UPD traffic
on your connections.

If it's still not working try to sniffer your network on both site's and
see if the packet reach the other site or if he even try to go over your
VPN connection.

Hey group,

We have 5 sites all linked via a VPN. When we came in this morning none
of our sites could ping via the DNS name, only the IP address. We
noticed on our VPN routers that the all ports are open except the
Broadcast ports?

Could someone tell me do we need broadcast on our routers for DNS to
work. If so what port do we need Open?

We have windows 2000 servers, and all the sites clients are on static
IPs

Many Thanks
Merlin
