13.4.2 Port Forwarding Screen
Click ADVANCED > NAT > Port Forwarding to open the Port Forwarding screen. Refer
to Figure 109 on page 296 for port numbers commonly used for particular services.
" Remember to define the appropriate Firewall Rules to allow the ports listed
on the Port Forwarding Screen through the correct WAN and LAN/DMZ
interfaces (e.g. WAN-to-LAN and Cell-to-LAN or WAN-to-DMZ and Cell-to-
DMZ rules).
" If you do not assign a Default Server IP address, the LAN-Cell discards all
packets received for ports that are not specified here or in the remote
management setup.
" In general, if you wish to access the LAN-Cell for remote management through
the WAN or CELLULAR interfaces, do not define a NAT Default Server. Use
the Port Forwarding Rules, Remote Management Ports, and Firewall Rules to
define WAN-based remote access to the LAN-Cell.
" The last port forwarding rule is reserved for Roadrunner services. The rule is
activated only when you set the WAN Encapsulation to Ethernet and the
Service Type to something other than Standard.
