NAT Forwarding

10. 1. Translate Address and Port by ALG

ALG (Application Layer Gateway) allows customized NAT (Network Address Translation)

traversal filters to be plugged into the gateway to support address and port translation

for certain application layer “control/data” protocols: FTP, TFTP, H323 etc. Enabling ALG

is recommended.

1. Visit http://tplinkmodem.net, and log in with the password or your TP-Link ID.

2. Go to Advanced > NAT Forwarding > ALG.

Note:

It is recommended to keep the default settings.

• 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

IP networks.

• FTP ALG: If enabled, it allows FTP (File Transfer Protocol) clients and servers to transfer

data via NAT.

• TFTP ALG: If enabled, it allows TFTP (Trivial File Transfer Protocol) clients and servers

to transfer data via NAT.

• H323 ALG: If enabled, it allows Microsoft NetMeeting clients to communicate via NAT.

• SIP ALG: If enabled, it allows clients communicate with SIP (Session Initiation Protocol)

servers via NAT.

• RTSP ALG: If enabled, it allows RTSP (Real-Time Stream Protocol) clients and servers

to transfer data via NAT.
