Hi,
I´ve troubles with configuration IMAP forwarding. I have such situation.

server1 (10.100.100.100) ----> orange (10.100.100.1) - green (192.168.0.199) -----> IMAP (192.168.0.7)

The goal is that server1 in orange net can connect to IMAP server in local LAN behind green interface of EFW. What else I need to set to get all it work?
I have one rule (first screenshot) in port forwarding and one inter-zone firewall rule (screenshot2).
Now the server1 cannot connect to IMAP. Can anybody tell what I have wrong?
Thanks a lot.

Hynek.
