      Inbound Http Access Broken

      Hi

      I have a CCTV server that allows me to connect to it and view a stream of mjpegs to see what's going on at home when I'm out.

      I can view these on any browser, but usually use my iPhone and an App called Cavu.

      All worked fine until my Sky router decided to download and upgrade its firmware. Thus removing all stored settings. I spent some time setting up my virtual servers again (allowing port 80 through to the CCTV server's LAN address) but I couldn't get it working again.

      I can see the feed from wifi on the LAN. But as soon as I switch to connecting from outside it stops working. Interestingly when I try to connect from outside, I'm prompted for my username & password and it authenticates me ok (if I send the wrong credentials it gives me an error), but no image is ever received.

      I figured maybe the new router firmware was the problem and, being more than a little put out at the way it lost all my settings during the upgrade, I ditched the Sky router in favour of a shiny new Belkin unit. This hasn't solved the problem.

      I can still use my slingbox, vnc and access my NAS (over http) from outside. I have tried changing to a different port and adding the CCTV server as a DMZ with no result.

      Can anyone else view motion jpegs across the net ?

      I running out of things to try - Any ideas ?

      Thanks

      I don't suppose you need to have the iPhone MAC address in the approved list?

      Hi

      Thanks for the suggestion.

      I've double checked and MAC address filtering is definitely off. I can also access the other services I mentioned from the iPhone.

      The security log doesn't show any blocked activity from it either.

      Question Re: Inbound Http Access Broken

      A quick update:

      Seems I can connect to my DVR from some wifi hotspots, but not others.

      Starbucks works, Marriott doesn't My mates adsl wifi works, my Dads doesn't. 3G on my iPhone doesn't work.

      I'm at a loss to explain it.

      Any ideas greatfully received.

      Most likely in the places it doesnt work there isnt sufficient bandwidth or the relevant ISP's have blocked the protocols your DVR uses.

      Re: Inbound Http Access Broken

      Just a thought, as I have no idea and have never dealt with this kind of thing, but I have some experience with networking. Sometimes some settings that are set up with one system work, and then when something changes, they no longer work; perhaps try setting the device to default settings, and reconnect, as if setting it up for the first time.

      Has it actually worked at those places before and now it no longer works, or have you just found that some new places you have tried it at, don't work? Basically, is it still working from the places it worked before?

      Thanks for your ideas.

      The DVR just uses mjpeg over port 80. The same protocol & ports as web pages, so I suspect it's not a protocol issue. Regarding the bandwidth, I can stream movies using Air Video & my Slingbox from the sites that don't work, so I suspect that's not the cause either.

      The DVR used to work fine over 3G and from my Dads. It stopped suddenly.

      You would be surprised how clever some of these traffic shaping systems have become, I have no doubts they would be able to specifically block MJPEGs whilst letting other things through.
