RE: ftp firewall filter

[Andrew Feigenson <andrewf technologist com>]

Sorry, I'm a little new.

I'm using Firewall Toolkit 2.1 and it was set up (by the person I 
replaced) right now to deny all traffic from the outside except for SMTP 
thru port 25.  It should also be letting everything from the inside 
through but is not.

Basically, I don't know enough about ipfwadm and the man page is not 
worded well.  I could really use some thorough documentation either on 
paper or a web page somewhere.  

Thanks,
A
