Chapter 11 NAT Forwarding 11. 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. Visit http://tplinkmodem.net, and log in with your TP-Link ID or the password you set for the router. Go to Advanced > NAT Forwarding > ALG. • 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. 43

NAT Forwarding
11° 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.
Visit
http://tplinkmodem.net
, and log in with your TP-Link ID or the password you set for
the router. Go to

ALG
.
•
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.
