I've created a rule to deny any traffic from my DMZ interface to my
LAN, using the Reject option in the WebGUI. However, when I save, I get
back to the firewall_rules.php page and there is a red 'X' a the left of
my rule, while it should be a yellow 'X'. If i try connect to the lan,
it looks like a block as I don't get a rejected connection up front.
I've created a Reject rule for my LAN interface and all is ok (yellow
'X', immediate rejection).
If you need more details, please let me know.
