Looking for help setting up Wireguard on AC1200 OPAL

Technical Support for Routers VPN, DNS, Leaks

Hello,

Im a total networking novice and im currently in over my head giving myself grey hairs.

Hoping someone can help me out.

Long story short my mother is retired and has dementia and ive been trying to work on a setup to help her and the family out as Im her main care giver.

The end goal I'm trying to do is join two networks remotely. One at my house and one at hers with a 2 way link.

I essentially want to give her access to plex and a home server I have here so she can watch dvds I've purchased and backed up for her to eliminate the possibility of her losing said Dvds .etc ( which is legal where i live just to be upfront.) as well as running onvif traffic from a few cameras she has to my home server for footage recording.

Originally I had a ghetto setup using a mini pc with tailscale as a exit node at her house but it kept power cycling and having issues.

So after googling I purchased 3 of the units mentioned in the title as I heard I could achieve this.

Ideally I would like to have one at her house, one at my house and one as a travel router.

I have spent about a week playing with this and Ive just broken my network and ran into issues.

So im hoping someone here would be kind enough to help a newb out.

I tried setting up two units as routers with wireguard and I think i got close but now the issue im running into is double WAN.

When i try to run it as a repeater wireguard seems to disappear.

I Thought about installing tailscale but the addon doesnt seem to be supported on this model.

Really hoping someone will help as my mother is on me daily about this currently, and Id like to help her be comfortable in retirement.

Thank you Kindly.

Please check this manual: Build your own WireGuard Home Server with two GL.iNet Routers - GL.iNet Router Docs 4

Make sure that both routers do have different IP addresses.

Thank you ive looked at that and from what i understand Im following it and getting no where.

Issue is both networks have pre existing routers I cant remove and im running into double wan issues.

If i switch to repeater I lose all vpn functions.

At this point Im wondering if im better off returning them and gettign a few pis to run tailscale.

If they have already routers and you can't modify them (so no port forwarding) you won't be able to run WireGuard for VPN. At least the server one needs to be reachable from the internet.

Ok let me more specific.

Currently At my house I have my modem > Opal > and Asus router and the server. I can change this However I need. This will be running the Wireguard Server.

The issue Im running into at my mothers is she has Internet > Opal >A Google nest Mesh System.

I can forward ports on all my hardware if needed.

Issue is I cant forward ports on my mothers google wifi mesh system.

is there a way I can forward ports from the Opal as a main router to the google wifi as a secondary?

I have full admin access to her modem and network as well as mine.

You don't need to forward ports on the network of your mother - in that case the WireGuard server must be on your side and she will get an client only.

So is the Opal connected to the internet directly here?
Which Google Nest Mesh System?

This seems the wrong way round, at your end the Opal needs to be a wireguard server only

At my mother's she has Google Nest WiFi - AC2200 with 3 points set up.

I'm new to all of this so I'm not sure of any of what I'm doing. How am I supposed to set it up as a wireguard server only?

I tried to bridge the modem at my mother's today and have the Opal as the primary modem and I lost all Internet connectivity. Had to completely reset the modem to stock and rip out the Opal.

Alright! I got the server running on my end and a client running at my moms! Turns out it was a issue with the ISP Modem, had to clone the MAC address to get it to get internet connectivity! Its been a trial by fire!

Lastly what do i need to set up now to be able to have her acess my home server , and so i can access her cameras .etc. Im assuming i need to do some form of routing? Anyone have a good guide on this .etc?

Currently I have all device traffic going through the wireguard on both devices, but i cant access her onvif cameras.etc yet... and have turned on access lan everywhere I can see it.

I have the Glinet router as primary on both ends with a public IP

Please simply draw a topology to show the network route of these onvif cameras from your mom home to your home.

DVD video can be transmitted, is it?
