Please help me set up a HomeRouter - TravelRouter set up.
I’ve bought a Flint to use as HomeRouter and a Slate AX as TravelRouter.
In the home network I’m behind the Spanish Movistar router for fiber.
First I tried the direct approach, I don’t have a static IP.
I tried port forwarding the 51820 port on my ISP router and it seemed that the Flint couldn’t use the NAT, so it wasn’t working, I also tried to use glddns, and the ddns test never worked.
After that I put the Flint on a DMZ behind the Movistar router and still the same, the glddns test never worked.
I cannot put the Flint before the Movistar router, as it is connected directly to the fiber.
So afterwards I decided to use Tailscale. I had to modify the code for the tailscale config in order to the flint to advertise its routes, so I could activate it as an exit node (Brume 2 as a Tailscale exit node - #7 by asksimple)
I did that an it was activated as an exit node. I tested with my mobile phone and it worked.
Now I’m trying to use my Slate AX as Homerouter and using the Flint as exit node.
I can see the Flint exit node and select it in Custom exit node.
However it doesn’t work. After I do that I cannot access the internet.
Afterwards I modify the Luci config in the flint according to the first comment here:
After I did this I cannot access anymore the Flint remotely, but I can still use it as an exit node with my mobile phone or other devices, but not with the Slate AX.
How can I make the Slate AX use the Flint as exit node?
