Hello!
We have a bounch of clients using Outlook (all different versions) behind a m0n0wall NAT.
From time to time their connection to the POP/IMAP server closed unexpectedly (from Outlook point of view), which makes it go berzerk

Is there any specific value for NAT timeouts in m0n0wall, or is it controlled by "TCP idle timeout" found in "System -> Advanced" ? Im using m0n0wall Version 1.231
