RV016 latest stable release, two active WANs. Using One-To-One NAT, port forwarding (via UPnP rules), firewall rules, etc. I get "Connection Refused - Policy violation" for IMAP at random times per day over a particular WAN (static IP wireless 2M/2M). Most of the time IMAP works but at least a dozen times per day it appears to stall and I can see the violation in the logs. Maybe 10 seconds later it is ok. The affected IP is the main IP for that WAN port. A UpNP rule for IMAP is in place and a firewall allow rule is setup followed by a deny all rule. Most of the time it works but these deny errors are very irritating and I can't make them go away. All other protocols over the same WAN port/IP and the other WAN work fine, only IMAP is giving this problem.
