Re: [FW-1] DNS Question



Have you check the UDP reply timeouts ? In case the replies are taking
longer than the timeout set on the firewall,
the would get dropped.

Subject: [FW-1] DNS Question


All,
    After all the IPSO upgrades and service pack upgrades for our
Nokia/Checkpoint 4.1 SP5a solution, we started seeing some random results
with our DNS servers.  Sometimes, it would fail on the first lookup - but
after that it would be ok... my question is simple... for the last several
years we've had the simple 2 rules for our DNS Servers:

1.    Any (Source)    DNSServers(Destination)    DNS-53(Port)
2.     DNSServers (Source)    Any (Source)    DNS-53 (port)

The question is simple...are we missing something obvious???  Our DNS
servers are Windows 2000.

Thanks in advance...

-Brian
