MSM7xx Controllers Configuration Guide v6.4.0

By default, the Internet port operates as a DHCP client (except on the MSM765 zl and MSM775
zl, where it must be manually configured). Select the option you want to use and select Configure.
See the following sections for additional configuration information.
• “Configuring the PPPoE client” (page 40)
• “Configuring the DHCP client” (page 41) (default setting)
• “Static addressing” (page 42)
Network address translation
Enable this option to permit all the computers on the network to simultaneously share the connection
on the Internet port. See “Network address translation” (page 62).
Limit NAT port range
When enabled, the controller reserves a range of TCP and UDP ports for each authenticated,
access-controlled user starting at port 5000, and maps all outgoing traffic for the user within
the range.
NOTE: If you enable this feature you should not assign static NAT mappings in the range
5000 to 10000.
Size of port range
Sets the number of TCP and UDP ports reserved for each user.
