PORT FORWORDING
The UCM6510 network interface supports router functions which provides users the ability to do port
forwarding. If the UCM6510 is set to "Route" under web GUI->Settings->Network Settings->Basic
Settings: Method, port forwarding is available for configuration.
The port forwarding configuration is under web GUI->Settings->Network Settings->Port Forwarding
page. Please see related settings in the table below.
Table 11: UCM6510 Network Settings->Port Forwarding
WAN Port
Specify the WAN port number or a range of WAN ports. Up to 8 ports can be
configured.
Note:
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.
LAN Port
Specify the LAN port number or a range of LAN ports.
Note:
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.
Protocol Type
Select protocol type "UDP Only", "TCP Only" or "TCP/UDP" for the forwarding in
the selected port. The default setting is "UDP Only".
The following figures demonstrate a port forwarding example to provide phone’s web UI access to public
side:
• The UCM6510 network mode is set to “Route”
• The UCM6510 WAN port is connected to uplink switch, with a public IP address configured, e.g.
1.1.1.1.
• The UCM6510 LAN port provides DHCP pool that connects to multiple phone devices in the LAN
network 192.168.2.x. The UCM6510 is used as a router, with gateway address 192.168.2.1
• There is a GXP2160 connected under the LAN interface network of the UCM6510. It obtains IP
address 192.168.2.100 from UCM6510 DHCP pool
