I recently installed a SA540 in front of my UC520. The SA540 is handling the internet facing traffic. The SA is using two interfaces WAN (public IP) and LAN (192.168.75.0/24)
I was able to get the UC520 working and clients are able to connect through to the internet, etc. Clients on the UC are either data (192.168.10.0/24) or voice 10.x.x.x
One of the reasons I choose to install an SA540 was for the firewall rules. When I create a rule I can enter an IP from the UC range but the SA540 does not seem to apply the rules to the traffic. The firewall rule creation only allows FROM: SECURE LAN to WAN or the other way around.
I am assuming the traffic is not being seen properly as the SA540 facing interface from the UC has a 192.168.75.10 address. If I setup a rule to block the MAC on this interface it blocks all traffic.
My question is how do I add the 192.168.10.0 range into the SA54's secure LAN zone so that traffic is affected by rules I create.
