How to open Firewall for non-UCS packages

UCS - Univention Corporate Server
,
#1

Hello,

I’m willing to develop J2EE applications for the UCS server. I don’t have local host access via a webbrowser.
I’m using Glassfish 5.0 as appserver. For administration goals I have to connect through port 4848. (Reverse proxying works for rhe applications but not for the management console)
However this port is filtered. Wenn I try to open it via iptables, no result!
can I use the ucr-command for 3rd party products or what is the right wat to handle this?

Thanks in advance.

I’m sorry,
It’s solved by ucr set security/packetfilter/tcp/4848/all=ACCEPT and restarting the firewall…
