viewing Lorex LH110 through a proxy server.

[hoser]

Hello Shane,

I have installed a Lorex dvr system for another person.  After some sweating with the 2wire, I was able to get it to work remotely.  Primarily problem was that the port forwarding software installed the Lorex app to the computer I was using to set up the system, I got it moved to the dvr and it worked fine.  My next problem is that the owner of the system cannot access the cameras at his place of business.  He is set up to run through a proxy server, he can get on the internet but cannot view the cameras, when he puts in the url for his cameras, he gets the Lorex page but it is black with the little icon up in the left corner.  I took my laptop there (can view his cameras with no problem from anywhere I can get on the net), got logged into his proxy, and when I attempted, I received a message stating that the page could not be displayed and I confirmed that I could get on the net.  He is running windows xp pro and IE8.  My laptop is running Windows 7 and I am using IE9.  I suspect the proxy server may be blocking his (and my) access.  What can he ask of his network administrator that might help with this issue?  Not worried about getting on with my laptop, just provided the info in case it would help.

Thanks,

Sounds more like his router doesnt like reverse nat

So when at the same network as the DVR just use the DVR local IP. When out side use the DDNS or internet IP

I guess I left something out, he has five stores, no problem getting on when at the store through the dvr, I learned about reverse nat from your forum.  It's his main store that is set up through a proxy that he cannot access the cameras.  If I can get to the Lorex page through the proxy, should I be able to see the cameras?  If so, would it be an issue with xp and IE8?  I never got the activex control request when on the the Lorex page for the first time with xp and IE8, I installed it manually but I don't see it in the add-ons list when I check.

[Shane]

Perhaps the proxy is blocking the activeX control. They do have that option. (Just like in my Linksys router)

Anyway you will be able to check the proxy server settings?

Shane

I was unaware that blocking the activex on the proxy was an option.  I did go into the security settings on the computer in his main store and changed the settings for both lan and internet to allow activex as I had to do for the internet settings when initially setting up to view on my laptop, but no luck.  I will check with the network administrator tomorrow.  The proxy is running through a 2wire I don't know if it can block activex but I will check that as well.

Thanks,

You say it is running through the 2wire. Is it simply using the built in 2wire functions or using proxy software?

The 2wrie has some options

And as you can see in my linksys I can block activeX

But again these are simple router options.

Any reason he is running a proxy that you know of?

It's a popular, nationwide auto parts franchise and they have their own system for accessing inventory, ordering from the warehouse etc.  He owns the hardware but they set up his network, so basically, it's their idea not his.  The store I put the cameras in has the exact same dsl modem and I could plug in direct and bypass the proxy but I wasn't able to do that at his main store, at least, not yet.  We did contact the network administrator today and he has no problem with what we are attempting to do which kind of goes back to the router settings and perhaps something they might need to do at their end.

Sounds like we need to double check a few settings.

I also already have the lorex active x control installed. Email me the DDNS name and I will see if it comes up for me.

Shane

[Shane]

OK it works for me. But not right off the bat.

Once I got to it I had to make sure compatibility mode was enabled.

After that IE asked me to install the activeX control. I said yes. Then after a little bit when it was done loading, IE decided to block the control since it wasn't signed. SO Had to go into IE security and change the permissions to allow the unsigned control.

After that I reloaded the page and the login screen appeared

(Win 7 64 bit IE9)

Where you able to get it to work like I had to?

Shane

I took a laptop that had xp and ie8 (same as his store) and installed the activex control with no problem (after changing security settings) and was able to get on to see the cameras at my home.  I then took the same laptop to his store, got onto his network, was able to access the internet and could even log into the lorex account page and log on to my account, but when attempting to go to the lorexddns page to view the cameras, the page would not come up at all, however it would come up on the computers in the store without the activex installed but there was no drop down bar asking if I wanted to install the activex control no matter what I did to the security settings.  So I am assuming that the ability to install and run non microsoft approved activex controls is being stopped by the network administrator or the dsl router/modem.  I also can't get into the dsl modem by plugging directly into it and I have never had that problem before with any other dsl modems and if I go to ipconfig, the router doesn't show.  The router is working as the whole store is running on it. 

[Shane]

2wire normally doesnt like reverse nat though

so if at the store and using the DDNS name could be the reason why it didnt work. While in the shop did you try the local IP instead since we know the DDNS works from the net for both you and I.

Shane

[hoser]

the store I was at was the main store, not the one with the cameras, so the same as you or I doing from home except the the main store is running through a proxy server.

[Shane]

Ah that makes good sense.

Then it is time to find who set the proxy up and get them to unblock the control

We confirmed it works otherwise.

I will be contacting the network administrator tomorrow.  I have run into 2 types of administrators, the very conservative who allow nothing because everything is a "risk" and those who understand the request and use their judgement, work with you, and attempt to assist.  I guess tomorrow I'll find what type I will be working with.  I'll let you know how it turns out.  I have already told the store owner that the most expedient solution would be to add dsl to another one of his 6 phone lines and use it for his personal use, right now they won't even let him get on with his smartphone to save on data rates over 4g and they cut off his ability to listen to music because "it uses too much bandwidth".
