[Snort-users] Proper Method and/or Place to Declare HTTP_SERV ERS port?

Actually, I think it would be a wonderful idea for the entire set of snort
sigs that contain source or dest port as 80 to be change to a variable.
We've also set up several other variables based on the fact that different
services have different ports in varying parts of our network... so one
hard-coded port wouldn't work for us.   It's worked out very well.

In this case I will create another var, say
var HTTP_SERVERS_PORT, set it to 8180 and
change 80 in the rules files to $HTTP_SERVERS_PORT.
Does anyone see a problem with this?

Thanks again,

Vadim
