    Default How to open "outbound" port

    Untangle latest version in router mode. Having trouble getting my 3CX (phone server) remote clients (iPhone, etc) to work.
    3CX says this: To allow users to use their 3CX clients remotely, be they on Android, iOS, Mac or Windows, you must open the following ports:
    Port 5090 (inbound, UDP and TCP) for the 3CX tunnel
    Port 443 (inbound, TCP) HTTPS*for Presence and Provisioning*
    Port 443 (outbound, TCP) for Google Android Push:
    Port 2195, 2196 (outbound, TCP) for Apple iOS Push*


    The inbound ports I have all set up in Untangle's Config/Network/Port Forward section. I'm not sure about what 3CX calls "outbound" ports, though - what does Untangle call that/where do I configure an "outbound" port?

    due to NAT (IPv4), very little is locked down in UT by default. Certainly, nothing outbound.

    TCP port 443 might be tricky, I think you'll need to move NGFW off of that.

    See #10 @ Port Forward Troubleshooting Guide

    Code:
    If you are port forwarding port 443 (HTTPS), try moving Untangle administration to another port so port 443 is available to be forwarded.
    Remove any Source Address and Source Interface qualifiers - 99% of the time these are misused.
    That is on the Configuration > Network [Services] tab https://wiki.untangle.com/index.php/Services

    That's what I thought too (about nothing outbound being locked by default).
    I have the 443 changed to a different port for a year now. Confirmed working on the alternate port, so 443 should theoretically obey the port forward.

    Thanks.

    Found a solution. Don't think Untangle was part of the problem at all. I followed the list from user @Lev here https://www.3cx.com/community/thread...-2-bugs.46501/ and now my IPhone registers and can call on LTE.

    Thanks Jim.
