thorg Posted June 13, 2014 Share Posted June 13, 2014 Hi I just installed CCTV and works except internet. This is business Talk Talk, router Technicolor TG 582n. Ethernet cable is good, laptop connected works, I set port forwarding on the router, but I cannot ping DVR. Message is: Destination host unreachable. the router has dvr on the network devices list, correct interface, IP address, MAC address, but there is no full connectivity between dvr and router. Day before same DVR was tested and connected to Virgin Media router, worked fine. Now while connected to Talk Talk router does not connect to the router. Subnet mask, default gateway, DNS were set correctly on DVR. Who can help? Perhaps Talk Talk uses different ports, or firewall issue?????

Cubit Posted June 13, 2014 Share Posted June 13, 2014 Technicolour? What a heap of s***e. I'd be sacking that off. Anyway, you make no mention of opening the relevant ports (unless I missed it). Quote Link to comment Share on other sites More sharing options...
Lwillis Posted June 13, 2014 Share Posted June 13, 2014 Technicolour are a heap of ***** but I've never had one that didn't work first time. I've noticed there's quite a few routers now with the loopback blocking turned on. Quote Link to comment Share on other sites More sharing options...
thorg Posted June 13, 2014 Author Share Posted June 13, 2014 I wrote I had set portforwarding in the router. Port 8000. This worked on Virgin Media router without any problems. I tried few ports and no luck. It is very weird I cannot ping DVR but router found dvr connected to interface, IP address and MAC address. I also see Technicolour is rubbish, very unfriendly user menu, but my customer has it, and probably cannot change. Quote Link to comment Share on other sites More sharing options...
Cubit Posted June 13, 2014 Share Posted June 13, 2014 (edited) But what about opening the relevant ports? Edited June 13, 2014 by Cubit Quote Link to comment Share on other sites More sharing options...
craigstory Posted June 13, 2014 Share Posted June 13, 2014 can you ping the DVR on the internal network? alternatively you could try set the DVR as the DMZ in the router and see if that allows you to access it which would then indicate a problem within the routers port forwarding.

Ronnie Posted June 13, 2014 Share Posted June 13, 2014 Oddly, we've struggled to commission an IP only WebWay this week over a TalkTalk line (residential).. Commission signal going out but nothing coming back in, ports opened and nothing still. Luckily it was the last straw for customer and now moving to BT.

Neutech Posted June 13, 2014 Share Posted June 13, 2014 Dump the router to start with, i replaced 2 of these last week and no issues with getting setup Are you using static IP or DDNS? Can you access DVR on LAN? Quote Link to comment Share on other sites More sharing options...

9651 Posted June 13, 2014 Share Posted June 13, 2014 We had this There's first one was a talk talk branded d link. Worked fine on the LAN, but opened relevant ports, but couldn't get it to work. Tried everything.... Then they got a technicolor talk talk unit. Eventually we got it to work. Proper **** unit. A quick google of port forward with these routers confirmed this!

JB_ Posted June 13, 2014 Share Posted June 13, 2014 While adding the rules to the router you haven't put anything in the trigger port have you? AFAIK its just start and end ports need filling(and udp/tcp) before clicking add. Quote Link to comment Share on other sites More sharing options...
PeterJames Posted June 13, 2014 Share Posted June 13, 2014 DMZ to the local IP of the DVR, thats all you can do with Technicolour Quote Link to comment Share on other sites More sharing options...
skywalker Posted June 13, 2014 Share Posted June 13, 2014 technicolour is the ONLY router on our blacklist! if a customer has one and wants remote access, we tell them they need to change it.as luck would have it, we also sell netgear routers Quote Link to comment Share on other sites More sharing options...
Cubit Posted June 13, 2014 Share Posted June 13, 2014 For our sins we have to use these shitty things. Getting the video over the lan and private wan works fine with no set up required. Having done some checking on one this afternoon, I can't see how you could use it for remote viewing over web. Don't prolong your misery, get shut.

I've noticed there's quite a few routers now with the loopback blocking turned on. could you explain loopback? it sounds like a few problems ive been having. and also.. do all you guys supply your own router when networking a dvr? a known, easy to set up router thats already configured before it leaves the office.

Cubit Posted June 14, 2014 Share Posted June 14, 2014 could you explain loopback? it sounds like a few problems ive been having. and also.. do all you guys supply your own router when networking a dvr? a known, easy to set up router thats already configured before it leaves the office. It allows you to, for example, access the router. So, with, again, for example, these shitty technicolor routers, when supplied by BT (in my case). Out of the box the default IP address is 192.168.1.254 This can be pinged. We have to disable loopback. This then stops us 'pinging' the router. It does not prevent us access to the router but by doing a simple ping test you could be mistaken for thinking the router is dead/not present.

Lwillis Posted June 14, 2014 Share Posted June 14, 2014 The loop back stops the customer from using the dynamic DNS we setup when they are on their own WiFi So they end up having 2 sites in the app for the same place 1-local (when on same WiFi as the dvr) 2-remote (everywhere else) So use the customers router. Had a few issues with Homehubs but nothing major recently same with the technicolour ones I've done quite a few now no issues. Quote Link to comment Share on other sites More sharing options...
timmo66 Posted June 14, 2014 Share Posted June 14, 2014 yes this is exactly the problem I was having with a particular site - unable to access from the lan, but okay on the wan is this always called loopback or different terminology for different brands?

thorg Posted June 20, 2014 Author Share Posted June 20, 2014 hey Im on site, I moved dvr ip to DMZ and still no luck. Customer has static IP. The shot screen: http://i.imgur.com/xk0fTKj.jpg Router found dvr, but I cannot ping it within LAN. "Destination host unreachable" Quote Link to comment Share on other sites More sharing options...
thorg Posted June 20, 2014 Author Share Posted June 20, 2014 I change setting in DVR to obtain Ip through DHCP, DVR got new IP from router, but I cannot ping it, I moved it to DMZ, it still does not work. I never saw so shi*** router Quote Link to comment Share on other sites More sharing options...
Lwillis Posted June 20, 2014 Share Posted June 20, 2014 Its not the router it just how you've set it up. Assign the DVR a device name and then re do the DMZ Quote Link to comment Share on other sites More sharing options...
