Hi All,

I have a 2820 with a Trixbox VoIP system sat behind it.

The Trixbox LAN IP is 192.168.25.60.

If I set the Filter Default Rule to "PASS" then incoming SIP calls (forwarded via Open ports) works okay.

If I set it to block, it doesn't work.

However, I have the IP for this trixbox in an IP Group which is set in the data filter to "Pass Immediately".

Anyone any ideas on anything I can check? All of my other LAN PCs are in the same IP Group and these can all get net access okay!

I've added a single firewall rule for the Trixbox as a single address and it now works.

It seems that the IP address isn't being recognised whilst it's in the IP Group - oddness!
