I've discovered today that I've done a stupid thing. I've just installed a surveillance system and found I couldn't see it online. Then I learned that wirless modems can get multiple IP addresses per day, which is why I couldn't connect as the dam thing was changing addresses all the time.

No problem, I thought, I'll just ask for a static address. I was told by the telco that static isn't possible on a wirless modem. The only solution is to have fibre to the door.

So, I thought I'd ask here, to see if there is any other workaround members may have an idea of please?

Who is your provider? 50+ sell wireless connections in NZ.

You don't need a static IP to access a remote system, solutions such as dyndns solve this very easily.

The bigger issue is that I assume you are using a port forward to access your camera system. If you are you should immediately disable this and should not be using this under any circumstances. It is an incredibly insecure setup.

Thanks Steve - Vodafone is the provider. And yes, I did set up port forward.

I'm reading up on what dyndns is now..............

More likely that connection is CG-NAT so port forwarding won't work.

Spark Max Fibre using Mikrotik CCR1009-8G-1S-1S+, CRS125-24G-1S, Unifi UAP, U6-Pro, UAP-AC-M-Pro, Apple TV 4K (2022), Apple TV 4K (2017), iPad Air 1st gen, iPad Air 4th gen, iPhone 13, SkyNZ3151 (the white box). If it doesn't move then it's data cabled.

In which case you just opened your internal network to all sorts of nasty security risks.

Do yourself a favour and disable port forward. If you want access to your cameras you have two options:

1. Use a system that does not need port forward

2. Investigate a VPN setup and connect to your network via VPN when needed.

Thank you - but it DID work when I first configured it. But later in the day it failed and I found I couldn't ping the IP.

I had no idea that wireless modems changed their address a few times a day (a techie friend told me this), so when I went onsite I discoverd it had.

So I'm just getting my head around EZDDNS, which is what this system uses and hope this will work.

I'm not in the tech industry so learning stuff as I go.

Question - can I establish a VPN if I have a wirless modem?

If the answer is 'no', then what do I need to do to make this so (said Picard), without having to change the plan to fibre, which would invovle me having the telco come along and install a fibre line to the premises.

You're missing the main point. It doesn't matter whether you have a static or dynamic IP or use DynDNS or something similar. If you have a system that has to port forward it is a massive security risk. You will end up as part of a DDoS attack on NZX or similar. Stop reading about DynDNS and look at the dangers of port forwarding and how insecure it is.

You can if you have a static IP address.

But no port forwards. Ever.

You can run a VPN client on another router, e.g., a Mikrotik, or any linux box, and point to VPN server in cloud or anywhere.

Assuming you just have a Vodafone modem there isn't a lot you can do to securely configure your system without remote access without spending $ on additional hardware. The connection and camera hardware you've chosen for your solution isn't really the ideal solution for your requirements.

I also thought all Vodafone FWA and RBI was CG-NAT so am surprised it could ever work.

Ok thanks all. It’s so disheartening to be told I’m not getting the point (when I do), that I’ve done it all wrong and that I shouldn’t have started in the first place. I don’t like being bullied. I’m sure the people that DDOS NZX don’t care about a small church but I do want to make it secure in case they happen to come along.

Thank you spyware for offering a solution but I don’t understand what you’ve said, sorry. I’m out of my depth and the time I have to watch youtube to get up to speed.

I’ve put literally hours in over the last 4 weeks drilling holes, running cable, getting cobwebs in my hair, home testing…… as I set it all up. All in my spare time. I’m learning as I go and I had no clue of this latest hitch. I’m trying my best.

This morning I went to Mitre10 to get a part to fix the shower. An assistant told me I was getting the wrong thing and gave me a solution. THAT was helpful. ATM I have no idea why my surveillance hardware is wrong; I just know I've been told it is.

I now realise I need to pay somebody to do this job correctly and that there are potential workarounds. I’ve done all the work for free to save the people I’m helping, but now I’m at my limit as I don’t know how….

Thank you all

I am sorry you feel bullied. This is certainly not the intention.

The idea is to implement something secure to avoid headaches in the future - something that can cost more at the end.
