Linksys 4000 - Disabling outbound SMTP except from Exchange Server?
I'm working with just a lowly Linksys business router (Linksys RVS4000), so I'm not sure I'm in the right forum. On the "IP Based ACL" page I have SMTP enabled on the Linksys from my Exchange IP address. I want to add a 2nd rule that excludes any outbound SMTP traffic from any other IP address on the network. Tried setting a Deny Any for the whole network and making that Priority 2 on the assumption the router would first honor outbound email from the Exchange Server and then stop anything else. However this configuration results in stopping all email. Any ideas? Thanks.

In Syslog I also se...
