• PPTP Pass-through: If enabled, it allows Point-to-Point sessions to be tunneled
through an IP network and passed through the router.
• L2TP Pass-through: If enabled, it allows Layer 2 Point-to-Point sessions to be tunneled
through an IP network and passed through the router.
• IPSec Pass-through: If enabled, it allows IPSec (Internet Protocol Security) to
be tunneled through an IP network and passed through the router. IPSec uses
cryptographic security services to ensure private and secure communications over

4. 5. 2. Share Local Resources on the Internet by Virtual Servers
When you build up a server on the local network and want to share it on the internet,
Virtual Servers can realize the service and provide it to internet users. At the same time
Virtual Servers can keep the local network safe as other services are still invisible from
the internet.
Virtual Servers can be used for setting up public services on your local network, such as
HTTP, FTP, DNS, POP3/SMTP and Telnet. Different services use different service ports.
Port 80 is used in HTTP service, port 21 in FTP service, port 25 in SMTP service and port
110 in POP3 service. Please verify the service port number before the configuration.
