Upgrading to R2C
I got the following errors:
Reloading filter… rule difference detected.
*** Notice *** Filter rules appear to be different now!
This may be normal if pfSense fixed a filter rule bug.
If you experience problems, run this command to restore
the previous version: tar xzvpf /tmp/backup.tgz -C /
pfctl: warning: namespace collision with <madison>global table.
Everything appears to be okay (I can't see any differences in my firewall rules, and my Alias called "Madison" still appears to be in tact.</madison>
Thanks, we are working on the issue. Peter's patch introduced this behaviior trying to fix negated rules.
So far it appears to be a cosmetic pf bug but we need to be absolutely sure. Please test your ruleset inside and out and make sure there are no problems with it.
