Chapter 2 Installing Your IP1200C 9
If your network is behind
NAT
or
firewall
, you can assign a
pseudo
IP address to your IP1200C. IP1200C has
preset UDP and TCP ports allowing communication to get through NATs and firewalls. In general, you do not
need to open ports on your network gateway or router.
If your network is in the
DHCP
environment, you can enable IP1200C DHCP function to obtain an IP address
automatically.
Note:
When you encounter one-way voice cannot be heard problem, the reason might be that the specific
communication ports for IP1200C been blocked. Check if the specific ports on your router are opened to
IP1200C. For 4-port IP1200C, open TCP 1100 port and UDP 1101-1104 ports. For 8-port IP1200C, open TCP
1100 port and UDP 1101-1108 ports.
