For security and economic purposes, the SMC7301TA supports Single
User Account feature (SUA). Multiple users in the LAN can share a public IP
address from an ISP, and the whole LAN will be viewed as a big “device” by
Internet users. However, servers in the LAN are allowed to provide services to
the Internet users if you properly configure the server’s p rivate IP address
“translated” to the corresponding service port number. For example, you can
set the FTP server’s private IP address mapped to port 21. Follow the steps
and the SMC7301TA will automatically complete the mapping procedure.
Note: Remember to set a fixed private IP address for each server providing
services to the Internet users, i.e., these servers can’t be DHCP clients.
