How do I set multiple public IP addresses with my PPPoE/PPPoA connection?

The External Alias menu is shown in the web interface only when IPCOP’s Red interface is set to Static. To access the External Alias menu and set multiple IP addresses, do the following:

1. First add the Aliases to the WebGui
   • Open https://IPCOP_IP:445/cgi-bin/aliases.cgi
   • Enter the Alias IPs
     Note: This only adds the IP addresses to the Web Interface ONLY
2. Now added them to the IPCOP system
   • Edit /etc/rc.d/rc.firewall.local
   • Add these lines to the START section

                 # PPPoe Aliases -------------------------------  
                 sleep 3;  
                 /sbin/ifconfig ppp0:1 [IP Address 1] netmask [IP Subnet 1]  
                 /sbin/ifconfig ppp0:2 [IP Address 2] netmask [IP Subnet 2]  
                 # PPPoe Aliases ---------------------------------

3. Reboot and test using ifconfig
