Hello guys,
I have a serious bug with firewall rules for my email submission port: From time to time the firewall closed the incoming connection to the submission port on my mail server. This is behavior really nerves. I put an extra rule set for opening port 587 for email delivery. Is it possible the automatic security rules closing ist from time to time? But I wanna it open for reliable email communication:
config rule
option dest_port ‘587’
option src ‘lan’
option name ‘submission’
option dest ‘wan’
option target ‘ACCEPT’
best regards
Olaf
