watchdog firebox has blocked ssh out

[Mr. Mailing List]

i used another port, i have port 21 on server
forwarding to port 22, but it seems to still block it,
unless, in putty, i choose "raw" as protocol.  i
believe the ssh protocol itself is being blocked?

is it possible to somehow come across as using http
protocol?
