[Spread-users] spread through firewall?

[Matt Garman]

Hi,

We would like to open the smallest possible hole in our firewall to
allow spread connections.  What ports need to be open, and what type
should they be (tcp/udp)?

For example, say I'm running a spread daemon on channel 4803.  I
obviously need TCP port 4803 open.  But I believe spread uses
additional ports as well---which ones?

Thank you!
Matt
