      Internal connections

      I've just moved from Virgin to Sky and am a little confused by the behaviour of my new Sagem Sky router.

      I have two computers connected to the router, one running linux, the other in XP.
      I run a web server on the linux machine, and have set up port 80 forwarding in the router to that machine accordingly.

      If I'm away from home and put:
      http://myWANipadress
      into a browser, I see my apache pages being served. Great.

      However, if I put:
      http://myWANipadress
      into my browser on my XP machine, on the LAN, I get taken to the router's setup web interface. I can't view the web pages being served by the linux machine on my LAN.

      The same is true for my sshd server. I can connect from friend's houses, but I can't connect from within my own home!

      What am I doing wrong here?

      Re: Internal connections

      Isn't there a bit of software for the MS machine to browse ext formatted disks? I'm sure it comes with the distro!
      It's a long time since I dabbled with Linux but I remember being able to browse the Linux box files from Windows.

      Re: Internal connections

      No, it's nothing to do with XP vs Linux - this system worked fine on my old cable router, and the only thing that's changed is the router.

      I'm 99% sure it's a config problem with the Sky router.

      Sorry, I seem to have misunderstood!
      But, when you said that they can't browse each other ..............

      Re: Internal connections

      Sorry - I shouldn't have mentioned that because it just clouded the issue and wasn't related.

      Basically, if I connect to my WAN ip from elsewhere, it gets routed correctly.
      If I connect to my WAN ip from inside the LAN, I just get routed to the router setup page.

      Re: Internal connections

      I wonder if this is the Sagem router not supporting loopback?
      Presumeably you can address the Linux box by its LAN IP address but not by its WAN domain address.
      My old D-Link router used to do this because it wouldn't allow loopback (addressing an internal device by going out to the internet and then coming back). All I got, like you, was the router login page.
      However, my Sky Netgear router does support loopback, as did my BT HomeHub.

      I'm new to Sky so can't advise on Sagem routers. Maybe one of the 'old hands' can?

      You won't be able to access it via your WAN address, this side of the router.

      Spot on. You would have to use 127.0.0.1 etc to access it.

      No Ged, that's the internal loopback address.
      What I'm describing is also (confusingly) called loopback but is going out to the internet to a domain that resolves back to the Router that sent the request.

      Some routers support this, some do not. My Netgear Sky router does - I watch my security camera that way.
