Firewall configuration for license server

Hi all
Did someone have experience to configure Comodo Firewall for FlexLM license server? There is process lmgrd which has listening port 27000. I tried different configurations in firewall (global rule for source port 27000 in/out TCP, lmgrd as allowed app, training mode, safe mode), but nothing helps, server still not responding. In KillSwitch I see repeated “SYN Received”, which never acked by server.
Everything works perfect if I disable firewall.
Please help, I can not have server with disabled firewall to make it working.

I found issue. Port for vendor daemon has to be opened also. Just let know if someone will see same problem.
