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?????

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).

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.

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.

But what about opening the relevant ports?

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.

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.  

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?

Ronnie, worth noting that BT also use technicolour on some commercials.
