We have currently Zyxel Zywall 5 as firewall with Kasey server.
There is NAT used in network configuration and everything is fine.
Except Zywall 5 can handle only 1000 sessions and that is not enough for us.

We have tried to use Cisco ASA 5505 and Draytek firewalls (as replacement for Zywall 5). Everything else works like a dream but remote control won't work. Not at all.

We have opened port 5721 in/out for kaseya agents.

So, could someone tell what kind of configuration is needed? For example if we use ASA 5505. How to configure to get remote control work?
