    I can access my home server from outside my LAN via <a href="https://.homeserver.com">https://<myserver>.homeserver.com but not from inside. I.e., when I click 'Remote Web Access' on the Launchpad of a client computer it tries and fails to connect to <myserver>.homeserver.com.

    After some research, I found that Loopback is broken on the DD-WRT build that I am using.

    Using Telnet into my router (Telnet 192.168.1.1) I entered the following command:

    iptables -t nat -I POSTROUTING -o br0 -s 192.168.1.0/24 -d 192.168.1.0/24 -j MASQUERADE

    Now everything works as expected. Remote Web Access on Launchpad takes me to my server (via homeserver.com) on the LAN, the same as connecting externally.

    That's fine. Using your browser just connect to <your server name on internal LAN>/remote. What you are trying to do is connect to an Internet address from your LAN which is within your LAN! Unless your router supports loopback this will not work.

    When I try your suggestion I get the error:

    403 - Forbidden: Access is denied

    I am curious about the 'Remote Web Access' function on LaunchPad. It tries (unsuccessfully) to connect to <myserver>.homeserver.com not to <my server name on internal LAN>

    Thanx for your reply. This is not a serious problem for me because I am able to connect remotely, but I would like to know why it doesn't work within the LAN.

    Do you know how I can find out if my router supports loopback, if so how is it enabled? I am using an Asus router RT-N66U running DD-WRT.

    This funcion works fine on another site I have worked on that uses an asus router also running DD-WRT.

    Thanx again,

    That's what Remote Web Access is, from the Internet not on your local LAN.
