USING THE CXI/CXI II OR MXE INTERNET GATEWAY
By default, the System IP Gateway IP address is the same as the L2 Switch IP address.
The CXi/CXi II/MXe Internet Gateway can be used to provide the following functionality:
•
Forwarding of local traffic to the intranet, by virtue of network list lookups
•
Forwarding of all other traffic onto the Internet.
In Figure 57, a L2 expansion switch has been connected to the Gigabit Ethernet Uplink port of
the CXi/CXi II. A router has been attached to the L2 expansion switch.
The CXi/CXi II System Gateway IP address needs to be changed from the default value so that
it matches the router’s IP address. This is necessary because the CXi/CXi II System Gateway
IP address is also the Default Gateway IP address used by the CXi/CXi II internal LX Switch’s
network list entry table.
The intranet may contain corporate servers and other 3300 ICP phone systems that will now
be reachable via IP trunking. Call Control uses the System Gateway IP address to reach those
other networks. The PCs and IP phones use DHCP Option 3 (which equals the L2 Switch IP
address) to reach known intranet, and unknown internet networks.
