3> Port Mapping
Usually, this method takes a dynamic n:n translation and not only the
IP address but also port number translation is performed. For
outgoing calls, the SIA2410R performs NAT for multiple hosts on the
local network after getting a single IP address from the remote
network. For incoming calls, the SIA2410R can perform NAT for
multiple hosts on the local network by using the single IP address.
NAT can be implemented to use a single address or multiple addresses.
Note:
NAT will turn RIP off, so the addresses of the SIA2410R are not
propagated to the Internet or other remote networks.
