I'm trying to determine the security risk associated with an external Lotus
Notes Servers replicating with internal Notes Servers behind the Firewall.
Since the replication session is udp based (port 1352 at the target end), 
what are the range of udp ports (presumably the upper range) that the source
end (initiating) will end up opening for the replication session.  I'm 
assuming that we don't have a peer-to-peer relationship where the udp port
1352 is opened at each end.  If anyone can clarified this session, I'd
appreciate it.
The other thing is security risk in conjunction with a client behind the 
Firewall doing a dialup session (XPC, PPP, or SLIP) to the external Notes 
Servers.  This appears safe.  Any comments, anyone.
Thanks in advance.
