For awhile I had been dealing with a sort similar issue....see here:

There where other issues with it as well but that was the most 
reproducible.  Also sshd didn't work to same remote host either.  I 
recently upgraded the server from 6.2 -> 7.1 including updated ports 
rebuild.  That fixed every nagging issue with the system including 
nat/routing stuff.  My best guess is there was some issues w/ pf in 6.2 
as no config files for application got changed including fw rules yet 
now it works.
