I have two OBi5vs devices and have questions about what ports to use for the second device. The first device is using the following ports:
Allow Outgoing:
TCP Ports: 6800, 5222, 5223
UDP Ports: 5060, 5061, 10000 to 11000, 16600 to 16998, 19305
Allow Incoming on UDP Port: 10000
Now, my question is what ports should I be using for the second device? Should I configure the router to use DMZ for the second device? Is there a security issue with using DMZ? Is there a different set of ports I should be using for the second device?
Thanks for your help in advance,
Jason
