I have a Cisco RV180 small business router. I am trying to make a set of outbound rules to block SMTP traffic on all devices except the Exchange mail server located at 192.168.16.3
I have attached pictures of the two rules.
Outbound rule #1 has priority of '1' and ALLOWS SMTP traffic from 192.168.16.3 (source) > ANY (destination)
Outbound rule#2 has priority of '2' and BLOCKS SMTP traffic from ANY (source) > ANY (destination)
With these two rules enabled, e-mail stops flowing. If I delete rule #2 the e-mail flows. Have I configured the priority correctly? I go to ACCESS RULES, Reorder, connection type 'outbound' and I move rule #1 to priority 1.
Thanks for any assistance
