Tailscale - completely noob question

Hello Everyone,
Sorry for being such a noob here but I am switching over to 4g
broadband again next week and I have been told that I will not longer
be able to remotely access my DVR or mini home server since the
provider does not give a public ip address like a traditional
broadband provider.  Am I correct in saying Tailscale would resolve
this issue somehow and allow me to view my camera system remotely?

Thanks in advance.

I would expect so, probably you will not be able to establish a direct
P2P connection but through a tailscale relay server it will work.

Yes, and yes.

Thanks, that's a relief. Is the setup quite simple?
Is the setup router level so that all my devices will start working as
if I was connected to the lan?

Some devices such as my alarm system I wouldn't be able to change any
settings or install relay software etc.

It should work - I have a 4g backup Internet connection, that is the
same..  its great for when I'm away, I have a couple of VMs running
Tailscale that route specifically through this.. in addition, I have
some smart plugs that connect through it, that allow me to power cycle
my main router and servers.

How long did it take you to set it all up?
When it comes to all this I am literally starting from scratch so I
hope it's as simple as installing software without any programming or
complex configuration involved.

You will be behind CGNAT and a VPN will work yes but you will need to
run a VPN client on each of your remote devices.

I'm behind CGNAt and I have to use tailscale to view my cameras. I
just have a spare computer at my house that I use as a server and
install tailscale on it. With that I'm able to access all my devices
at my home. Very easy and quick setup.

Yes, you can use a server on your LAN as a subnet router, so when
accessing from outside, you can access everything on your LAN.

You don't need to run a client on each remote device if the remote
devices are all on the same network, you can just use one of them as a
subnet router.

The OP is asking about remote access

And what's the point if they're on the same network anyway?

----------------------------------------------------------------------

That's perfect. I already have a windows 11 server running continously
so I'll try and install onto that.

You didn’t understand it. OP is changing his home connection to one
that doesn’t have a public IP. He mentioned two devices that need to
be accessed, if they are on the same network, only one of them needs
to have it installed.

Also check r/Tailscale for doubts.

I brought a cheap 4g WIFI router from Ali Epxress foe about £20... the
headset part was just getting the SIM setting, everything else was
easy... but I've not tied the 4G directly into my network, rather it's
just acting like a wireless hotspot..

Being off the main network is what makes it so useful from a backup
perspective.

Yes, exactly that.
