[BlueOnyx:21416] Can't SMPT or SSH

[lewisg at iglou.com]

Strange (to me!) problem...

A 5209R server is on the same /29 subnet as most of the email users who
are behind a router on another IP address. Users on that network can ping
and connect to web services but SMTP and SSH connections time out. Outside
that subnet everything seems to work OK.

I have tried turning off DAR2, Login Manager, AV-SPAM and adding the
sublent to the whitelist in Login Manager.

I'm at a loss. Any ideas?

TIA!
