Matrix: Can I set the IVC-32 card external TCP/IP port address to be different to internal 6001
Using EHX v8.5.0
We need to set the IVC internal port to something different than 6001 (we’re using 6003-6004) and IP trunking does not work.
IP trunking works only on 6001 . Can you double check this for me using EHX v8.5.2?
Remember that we have 2x IVC-32 cards on each site 1 card connects using port 6003 for such trunking, while the other should connect through port 6004.
Solution
Yes you can set the ports to 6003 or 6004
I used the following firmware setup
EHX v8.5.2
CPU = 11.39.2.0
IVC-32 app = 7.20.5.0
IVc-32 Internal Local side = 192.168.65.22 (IVC card ) TCP/IP = 6001 internal
IVC-32 External side = 10.50.5.18 (IVC card ) TCP/IP = 6300 external 
Picture of my router/ gateway port forwarding rule (note you need to set protocol BOTH TCP & UDP )
IVc-32 card with external TCP/UDP port set to 6300
A download (apply changes to Matrix) with reset might be required whenever you change the External IP settings of the IVC-32 card
