Port Forwarding to Router Behind 2Wire
I have a personal router (Asus RT-N16 flashed with TomatoUSB) behind ATT's
2Wire 3600HGV DSL gateway/wireless modem. I am trying to set up port forwarding from the Internet to devices that are connected to the personal router.
The 2Wire uses the default 192.168.x.x subdomain. I have the wireless access capability turned off and the only device attached to it is the Asus router. The 2Wire LAN port is connected to the WAN port of the Asus. The Asus creates the subdomain 10.10.49.x.
Within the 10.10.49.x subdomain, the Asus acts as:
(1) Wireless access point
(2) DHCP server
(3) Dynamic DNS (DDNS) maintenance on FreeDNS
In order to update FreeDNS with changes in the 2Wire's public (WAN) address, the Asus must know the public IP address of the 2Wire, so I set up the Asus to assign the 2Wire WAN address to the Asus WAN port.
I have several services on my 10.10.49.x subdomain that I want to access from the Internet. They include an OpenVPN server at 10.10.49.11 listening on port 443.
How do I forward requests on the 2Wire's port 443 to the OpenVPN server (at 10.10.49.11) behind my Asus router?
