NOTES:
DDNS service will not work under these conditions:
• When the xDSL modem router is using a private WAN IP address
(192.168.x.x, 10.x.x.x, or 172.16.x.x), as indicated by a yellow text.
• The router may be on a network that uses multiple NAT tables.
4.3.7 NAT Passthrough
NAT Passthrough allows a Virtual Private Network (VPN)
connection to pass through the router to the network clients.
PPTP Passthrough, L2TP Passthrough, IPsec Passthrough,
RTSP Passthrough, H.323 Passthrough, and SIP Passthrough
are enabled by default.
To enable / disable the NAT Passthrough settings, go to the
Advanced Settings > WAN > NAT Passthrough tab. When done,
click Apply.
