Setting up 2 Beryl Routers

Hi everyone!
I have posted before but now I have a new question & needing help…

I bought 2 Beryl AX3000 routers, I am planning to use 1 of them as a travel router for my trip to Costa Rica in a few weeks. I was told that somehow I can set up the routers in a certain way to have the travel router that I’ll be taking abroad to connect back to my home ISP to reflect my home address IP (in the USA) instead of the IP address for the Air BnB in CR. Is this true?

If so, can someone either please explain thoroughly how to do this set up or reply with a detailed video or article link on how I can set the routers up successfully to show my IP address as if I were home.

Also, I am aware that my home ISP must be public but how do I know? Is there a way to check that?

Thx in advance to everyone who replies. I appreciate it! :slight_smile:

Hey admon/anyone else who comments (lol),
I am reviewing the link above you provided and I think I am having an error. When I click the link for IP.GS to see if my home ISP is a public IP address and it is giving me the screen that’s shown… what does this mean?
It’s happened when I try from my laptop and my cellphone.

That is a IPv6 address. It could be that you don't have a public IPv4 address.

Is there a way to find out if I have that? I tried to call the ISP but they aren’t understanding what I am needing to be able to tell me if it is public or not..

If it’s not public, will it not work?

What ISP do you use? What kind of connection? Cable?

Hey,
I use Spectrum Network, in the Midwest of the USA. The modem is connected to a cable which is coming from outside somewhere, then the router is connected to the modem using a cord also.

Possibly you are better off with https://ip.sb/ (like in the screenshot of the documentation page). The ip.gs only shows whatever IP you connected with, but does not seem to feature anyway to show both IPv4 and IPv6 addresses.

For me it also just shows IPv6 addresses, because my connection is fully dual-stack. In that case it can show by default use IPv6 and therefore ip.gs show IPv6.

Hi, when I pressed that link it shows the IP6 and then IP4 says not supported. Does that mean it is not public? I am not familiar with that the terminology means (ip6 vs the ip4)

It means that you don't have any IPv4 address. So there is nothing that could be „public“

IPv6 can work fine for VPN, but right now there is no tutorial availablr and some GL routers have issues with IPv4 as well.

Having just IPv6 is pretty weird. Not all sites support IPv6 (this forum for example only has IPv4; only A-records and NO AAAA-records)! If you do not have any IPv4, you should not be able to visit this forum.

The IPv6 you have shown earlier is a public IPv6. However your modem likely contains a firewall to block incoming traffic, so you would need to look how you can make a rule to allow that traffic. That's a bit like setting up a port-forward for IPv4.

Also having only IPv6 on your home side would require you to have IPv6 in the AIRBNB, so the 2 routers can use IPv6 to communicate. Without IPv6 in the airbnb the router there cannot connect to IPv6 addresses.

The setup itself is the same as in the guide. The only difference is that instead of endpoint=SOMETHING.glddns.com:51820 you would have a IPv6 address instead of the "SOMETHING.glddns.com"

is the best option for me is to set up my expressvpn account on one of the routers to just reflect an USA ip address? Thanks for explaining everything :slight_smile:
