[BlueOnyx:19504] Re: SMTP connection problem

[Lewis Gardner]

A bit more info and question.

Running "tcpdump -i eth0 port 25" shows connections from outside the 
7x.1x2.59.64/28 network but shows no activity when a connection is 
attempted from 7x.142.59.66.

I'm assuming the output of tcpdump gives connection information prior to 
any firewall, filtering or other configuration in the BlueOnyx 5208R. 
Correct?
