Re: HOME_NET and EXTERNAL_NET

[Tim Slighter <tslighter () itc nrcs usda gov>]

It might help too to tell us what alerts are firing off for this 
particular config.  Many SNMP, WEB, and other rules files will fire off 
alerts for the $HOME_NET whenever a connection is either intitiated 
outbound or if a valid incoming connection dynamically uses a port that 
fires a backdoor.rules TCP/UDP port
