Not available outside your network, advice

[monkeyboy72]

Hi, I had my PMS on a Nvidia Shield and have today set it up on my TNAS instead, everything great apart from I'm unable to access outside of my network.
I'm pretty certain this is a router issue but is there anything in TOS that I need to enable etc because I've exhausted everything in my router settings??
Thanks

Resolved, was nothing to do with NAS or Router was my ISP using something called CGNAT, have swapped SIM card and all good.

I'm curious. Who was your ISP? Most cable/mobile/FTTP ISP will be using CGNAT these days. How did "swapping SIM card" help?

I ended up getting a fixed IP address at (nominal) extra cost. However, my cellular router backup is still a (minor) issue.

I was having issues with a Smarty sim which even though runs on the 3 network uses CGNAT.
After lots of investigating turns out if you use an actual proper 3 sim (which I now have) then everything works fine
It's a quiet technical and beyond me but apparently a lot of MVNO carriers have this issue.

That (sort of) makes sense to me. I can't get 3 in my area. A lot of the providers of cellular based broadband seem to use 3 network as carrier.
