Port Forwarding (Ucm6102 Only); Table 12: Ucm6102 Network Settings→Port Forwarding; Figure 21: Ucm6104 Static Route Configuration - Grandstream Networks UCM6100 Series User Manual

In this network, by default the IP phones in network 192.168.69.0 are unable to call IP phones in network
192.168.66.0 when registered on different interfaces on the UCM6104. Therefore, we need configure a static
route on the UCM6104 so that the phones in isolated networks can make calls between each other.

Port Forwarding (UCM6102 only)

The UCM network interface supports router function which provides users the ability to do port forwarding. If the
UCM6102 LAN mode is set to "Route" under web GUI→System Settings→Network Settings page, port
forwarding is available for configuration.
The port forwarding configuration is under web GUI→System Settings→Network Settings→Port Forwarding
page. Please see related settings in the table below.
Specify the WAN port number or a range of WAN ports. Unlimited number of ports
can be configured.
Note:
WAN Port
When it is set to a range, WAN port and LAN port must be configured with the
same range, such as WAN port: 1000-1005 and LAN port: 1000-1005, and access
from WAN port will be forwarded to the LAN port with the same port number, for
example, WAN port 1000 will be port forwarding to LAN port 1000.
LAN IP Specify the LAN IP address.
