I'd like to know which proto's are used by which services. Right now I'm forwarding both tcp and udp, but are all those needed? The services I'm forwarding are listed below. Would anyone single out the ones that require tcp/udp? smtp http https pop3s imaps ssh I also forward a range of ports to my workstation so that incoming file transfers would work with the Licq client. Is there a more elegant way of achieving this? Many thanks, -- Arcady Genkin i=1; while 1, hilb(i); i=i+1; end To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
