Advanced Configuration appropriate servers (computers). Before using forwarding, you should assign static IP addresses to the designated servers. If you need to forward all ports to one computer, click the DMZ tab. Security > VPN Passthrough VPN Passthrough IPSec Passthrough Internet Protocol Security (IPSec) is a suite of protocols used to implement secure exchange of packets at the IP layer. To allow IPSec tunnels to pass through the Router, keep the default, Enabled. PPPoE Passthrough Point-to-Point over Ethernet (PPPoE) Passthrough allows your computer(s) to use the PPPoE client software provided by your ISP. Some ISPs may request that you use this feature on the Router. To allow PPPoE Passthrough, keep the default, Enabled. PPTP Passthrough Point-to-Point Tunneling Protocol (PPTP) allows the Point-to-Point Protocol (PPP) to be tunneled through an IP network. To allow PPTP tunnels to pass through the Router, keep the default, Enabled. Click Save Settings to apply your changes, or click Cancel Changes to cancel your changes.
