Although, not necessarily a Tomcat question...
If you are referring to that server also being a DNS server, you need to allow UDP 53 for DNS queries, TCP 53 for transfers, zone updates etc. If it not a DNS server and cannot make DNS queries (hostname lookups or whatever) then you need to allow destination port 53 UDP outbound allow.

We are running some application on serverm which has almost all ports blocked (except port 80 for http). Now, host-names lookup don't work on this machine, and I don't know which port must be opened. Can somebody tell me which ports are required for this? thanks very much. --- Odchoz� zpr�va neobsahuje viry. Zkontrolov�no antivirov�m syst�mem AVG (http://www.grisoft.cz).
