FW 3.3.5.2 Problem was created by legal
Have just upgraded from 3.3.3 which was working fine!; however now we seem tyo have Firewall problems - we have a smtp server behind the router and outgoing is working fine but there seems to be a block on incoming emails! - I have Firewall rules set up to block all incoming port 25 then to allow port 25 traffic from 2 specific IP ranges (these are the 2 external mail servers that filter our incoming emails). Any thoughts on what is different with the new FW?
Thanks

Couple of reboots of the router seems to have resolved the issue!

Check the session count on those two filter rules, if it's set to 0 it could be causing those problems potentially?

Strange - just logged in to check & the Firewall Rules have disappeared!! - not sure what the F/W has done but it has applied "Strict Firewall" and only now has the 2 Default Rule sets (I had several other sets when updated!) I kept a config back up - can anyone help as to how it is recommended to resolve this? The other settings of the internet connection, network, back up 3g etc are all there - it's just the firewall that's lost the rules (on the reboot).
