If you can set up so the CCTV is viewed via cloud p2p it might be easier. I found via port forwarding always seemed to drop connections. I have hikvision dvr and works seemlessly via this route.
I’m not a pro so other maybe able to help with the port forwarding route |

Not familiar with this particular router but I guess I can throw some ideas out in case there's something you've not tried...
I'd start by trying to identify where the actual issue is as you effectively have 4 different points of failure, each of which could have 1 of several issues. Simplest way to do that is often to rule out what you can. Working backwards, the CCTV presumably uses "special" ports so have you tried connecting a simple web server to the network and forwarding port 80 ? That way you can rule out/in any issue specific to the ports being used. Does the machine hosting the CCTV service have a firewall and is that set to allow connections from IP ranges outside the local ones ? (I'm assuming you can access the service internally) Can the machine hosting the CCTV service access the internet ? A bad configuration or internal firewall/"child safety" feature may block this. If so, check that it can open a connection using the custom port(s). Some routers have a DMZ option as well as port forwarding and often that will overwrite port forwarding. Make sure that's not the case and, if not, try using DMZ for the CCTV instead of port forwarding. It's not really safe to do so permanently but a good way to test the router. The router may have a firewall configuration that conflicts with the port forwarding, if possible disable it as a temporary measure and see what happens. If the router has the ability to respond to ICMP on the WAN port (ping and trace route) turn that on and see what happens when you try a traceroute to the WAN IP address. It's always worth trying traceroute with your custom port number(s) from the remote terminal too as that may give you a clue where it's breaking down. Some ISPs/carriers are good at blocking ports they deem as insecure without telling you and trace route may reveal if the is the case if your packet isn't making it as far as the router. http://www.yorkshireoffroadclub.net/ |

Whatever the tech support says, port forwarding is a massive ballache on a 4g modem as they do strange things with proxying and port forwarding, and don't admit to it!!
Maybe worth setting up an rtsp stream from the modem, so it's pushing it out? Alternatively, the hikvision kit has its own dynamic IP service that seems to do a good job tunneling through most things! |

Thanks all.
I've tried a lot of the suggestions above: (in no particular order).... make is Alien DVR from SystemQ. I've installed dozens of these ones so know their OS fairly well. They come pre installed a dynamic IP type of thing (IPpostcode they call it), where you setup via systemQ's own server with your dynamic IP addres and they give you a fixed login address (in the form of machine-serial-number.ippostcode.com) and this enables you to get around not having a static IP On sites where they have static IP (and this 4G router also does) you can usually just log in with the IP address no problem (apart from this 4G one) The DVR box uses ports 80, 1240 and 8240 as factory settings, but you can easily change them. I've tried 8080 instead of 80 as sometimes 80 clashes (and numerous other combinations as well) but they all come back as "closed" when trying a port checking site. It's as if (which I think it is) vodafone don't allow access back up to the router via their network OUtbound internet access is fine. Plug my laptop in and surf away. the DVR also has outbound access as I've setup an alarm for an internal camera that sends 3x pictures out if it's activated. this works just fine.
I've not looked at this one. ^^ I don't think they're (this make) usually set to block anything, but I'll check again when I visit the site this week.
Yes this router has DMZ settings but I've not really used them in the past, so it's a bit of a learning curve for me... care to give me a quick run down? 
@ Mick... I think your friends nerdy mate is on the ball with that one. I've read a lot of forums on the web and they all seem to point to services being proxied, eventhough when I spoke to a vodafone tech person they denied this. Funnily enough we use some data only SIM cards at work on fruit machine OLGA data units, and I spoke with the supplier of those SIM's... they can supply a totally access free card but it's approx 4x the price of the voda one  |

Does the router have different protocols for 4g?
Vodafone 4g doesn’t stop any of my remote access Mike |

^^^ AFAIK it doesn't have anything different for 4G, not that I can see anyway.
I went to the site and had another play today, to no avail. Took an O2 SIM card out of one of our work machines that uses a 4G data transmitter, to see of that would help, but it didn't (although as I got about an hour away from the site I remembered that I /may/ not have re-setup the IPpostcode thing for the new SIM which may/may not have made any difference. MSE... can I ask how you set yours up? How do you remote access it? straight to the IP or using another protocol? |

DMZ is not normally used but is the routing equivalent of connecting the target machine directly to the internet/WAN. Instead of forwarding individual ports it effectively routes all IP traffic coming from the WAN to the target machine regardless of port. If it's already configured on the router to point at another device then your port forwarding will be ignored/overwritten in most routers. By the same token if it's not already configured, if you configure it to point at your CCTV device it may work where port forwarding doesn't although it's not something you want to leave configured like that ! Many service providers do filter out traffic on what they deem high risk ports, I'd be very surprised if they're filtering out port 80 though. Did you try running traceroute ? http://www.yorkshireoffroadclub.net/ |

I tried DMZ yesterday which didn't work either (although at that time I hadn't reset the IPpostcode thing which I think will be IP specific...
) So I'll try and get back there today and have another stab.
I've not run traceroute, not really sure how it works so the results from it would be a bit meaningless to me. |

traceroute gives you a list of devices/routers that the packets pass through together with the time it takes. It means you can send a packet on a specific port and see where it stops if it's not working as the routers are listed in the order they are encountered.
As an example, if I run a traceroute on defender2.net from here you can see my outgoing router is at 192.168.0.1 and there i some delay (three * characters) in opening a connection from my ISP's router (zen.net.uk) to their outgoing router before it heads through as29550.net before reaching it's destination at the server that runs this forum - server1.web-rover.co.uk traceroute to www.defender2.net (94.76.204.86), 64 hops max, 52 byte packets 1 192.168.0.1 (192.168.0.1) 0.863 ms 0.559 ms 0.453 ms 2 vt1.cor2.lond1.ptn.zen.net.uk (51.148.72.22) 12.465 ms 12.750 ms 12.504 ms 3 * * * 4 51-148-73-55.dsl.zen.co.uk (51.148.73.55) 13.187 ms 15.807 ms 12.481 ms 5 ld5-linx.as29550.net (195.66.236.223) 13.706 ms 14.037 ms 13.476 ms 6 ae1-cr1.rdg.as29550.net (91.186.5.241) 13.957 ms 14.965 ms 14.347 ms 7 b.3.magic-hex.as29550.net (92.48.95.62) 15.685 ms 14.932 ms 14.459 ms 8 server1.web-rover.co.uk (94.76.204.86) 15.796 ms 14.581 ms 15.557 ms If you run something similar to connect to your CCTV device it may well show where the connection is breaking down (if it is). http://www.yorkshireoffroadclub.net/ |

Ah cool. I'll do a little research and try it out.
I just tried it here, got (understandably) different results to you up until the trace left my LAN and hit the wide world, then from your #6 mine was almost identical. So I'm assuming if I were on an outside network from this router I have, and do a traceroute to it (it has a static IP) then I may find a/the block? |
