External connections fail
« on: September 29, 2019, 07:44:13 am »
I'm setup Zentyal on new computer, and open 993, 143, 25 ports on my mikrotik router, NAT also configured on router.
Next I add one mail user and setup The Bat mail client.
I use free ddns domain mydomainname.hldns.ru and have white IP.

When I try to connect from internal network to mail server - it work fine.
But when I try to set  server address as mydomainname.hldns.ru or IP then connection fails.
Rules on mikrotik work fine, ports open and NAT-ed (i have second win-server, it work fine).
What need to set in Zentyal to set connection work from internet?
Zentyal firewall - all rules is ALLOW for all ports.

Why external connections not work? In local network all work good.
