Thanks Q*bert,

That helps out a bunch! I really appreciate the time you have taken to explain
everything. I'll have the firewall ports checked out. I think since it's
a new server it might not have been added to the appropriate access control
list yet - allowing the passthrough you mention.

Again, I appreciate the help.
