[Snort-users] Use dyndns to ignore my ip

Depends on your setup. Ideally you should monitor the inside of your
network (like behind firewall) so you only see stuff really getting in
which would mean this is a problem as you can just set your internal
network as the $HOME_NET variable.

However, if you want to see outside or you are using a software firewall
with it included (like pfsense although this should autowhitelist your IP)
you can perhaps look at your current IP in a whois query.

This hopefully should point to your ISP and give you their ranges which you
can add to your $HOME_NET variable. Obviously you will miss anything coming
from their ranges now though as a downside.

Unfortunately DYNDNS type services won't work as snort whitelists are done
by IP. May I ask about your setup? Have you build a sensor from scratch
like using security onion or built yourself or are you using software on
something like PFsense, untangle etc?). Also is this a home or business
type network you want to monitor.
