remote admin access?

    Tomato version 1.27 on ASUS 520GU router, ATT DSL internet.

    My DSL modem has local ip of 192.168.1.xxx. My router has IP 192.168.2.1. I have set up a DDNS on tomato interface and I can verify that my DDNS URL points to my modem's external IP correctly. I also enabled remote admin access with port 88.

    However when I tried to access my router's interface using my DDNS URL with port 88, it failed to connect to the router's admin interface.

    Is there anything else I need to do to enable this remote admin access?

    Thanks!

    You need to either set your modem to bridged mode or configure it to forward inbound port 88 to your router's IP - right now you're doing double NAT and not getting past the modem from the outside.

    Thanks Rodney.

    My modem seems don't have port forwarding. If I set the router to 192.168.1.1, will that solve the issue?

    Another thing, I have pap2 installed behind router, in tomato I set port forwarding of 5060 to the pap2, it is doing fine. So the modem just pass port 5060 to router by default?

    The IP isn't the issue - the double NAT is. If you can't do port forwarding with the modem, you definitely need to set it to bridged mode and do your PPPoE or DHCP to the WAN directly from Tomato.

    I don't know why the 5060 port forward is working unless it's using uPnP and that's somehow traversing. What subnet are your clients (behind Tomato) on?

    All devices behind tomato is using 192.168.2.xxx, DHCP from the router.

    In the modem, I found an option: Let LAN Share Internet Address. Currently it is set to 'No, use private IP address'. I guess I can set it to 'Yes, use public IP address' so it will be in bridged mode?

    Thanks!

    Unfortunately every modem uses a different method to set it up to be bridged - a bit of Googling for your specific model # will go a long way for this one. (A bit of Google-fu on the option you indicated suggests that this does not enable bridging.)

    Googled my modem model and found the solution: set the PPPOE location not on the modem. then set PPPOE on tomato.

    Thanks!
