That seems a bit odd. 
Is the GMS communicating with the GW server?
If so, the only port that should be needed for the device connections is 443.
You are connecting devices with port 447? Seems like that could be problematic if they are running on wifi behind proxies or firewalls.
Are all of these services running on one server?
If I do have to have two different services using the same port on one server, I usually bind a secondary address and make sure each service is listening exclusively on it's dedicated address so I don't have to worry about using non-standard ports.
Also, I usually proxy all of my webservices, so my external ports are always 443.
I don't do a lot with the local server firewall, but if you allow sshd it will external access, and it would be a pretty good model for allowing other services externally.

A quick question:

I have installed a SLES 15 SP2 machine, with GW Web on it, and commercial certificate - all working good.

I have installed GMS 18.3.2 on it, with commercial certificate, but devices will only connect if the Firewall is switched off.

I have "External" on the Firewall set with ports 4500, 8120,443-447, 7191   GW Web connects via port 446 (443 is used on the GroupWise Server for the old Webaccess still) and the mobiles connect via 447.

Is there something else I am missing on the Firewall side of things with SLES 15? I can't seem to find any documentation on the SLES 15 Firewall (Yast) for GMS.
