rsync makes an outbound connection to port 873 on the remote rsync
server
no inbound connections are attempted.
it would seem improbable that any special firewall rules would be
required.

I would expect that it is physically impossible for a server to block
local outbound traffic or inbound traffic to any port which it has not
opened and acquired inbound control over.

It remains possible however that the fx firewall gets confused by
particular packet allow/deny sequences if/while it is trying to be
"stateful" about its ftp, or other, connections.

Are there any tricks to getting RSYNC working through a firewall?


A number of people have said it doesn't work.

Did you need to reconfigure your firewall for it to work?

Has anyone ever tried porting ETHEREAL to OS/2? 

http://www.ethereal.com

I'd really like to try this program.

Apparently the Win32 version works using Odin...

Would you consider that a bug in FTPServer?


How can this work anyway? Does FTPServer block the port that RSYNC uses?
