I've configured a Protocol Rule for Outbound DNS in ISA, but DNS-queries are still blocked.

On our internal DNS-server we have DNS-forwarders configured.

In the FWSEXTDxxxx.log I see incoming DNS-queries on the ISA-server (=def.gateway).

But when I do a DNS-lookup, nslookup tells me: "DNS request times out".

My FWSEXTD-log tells me the following:

192.168.101.200 - - N 2003-12-04 12:41:06 fwsrv GATE1SERVER - - 212.115.192.195 53 61985 - - 53 UDP UdpMap 20000 - - - 925 8824
192.168.101.200 - - N 2003-12-04 12:41:06 fwsrv GATE1SERVER - - - - 61985 - - 0 UDP Bind 20001 - - - 925 8824

Anyone who has an idea why this connection is terminated abnormally (sc-status=20001)??
