Can't connect to LAN via TailScale - help wanted

chudak

Hello all,

I've been using TailScale for a while and am generally very happy with the experience.

I connect from iPhone and iPad with no issues and can ping/access my boxes on LAN

Advertised Routes:
192.168.90.0/24
192.168.20.0/24

I've set up my ubuntu laptop as well, but it can't ping/access anything on my LAN.

When I start, I see:

sudo tailscale up
Some peers are advertising routes but --accept-routes is false

I was reading https://tailscale.com/kb/1019/subnets/#enable-ip-forwarding and maybe don't have IP forwarding.

I wonder if I follow those steps and something goes wrong, how to remove all added items from /etc/sysctl.d/?

I also wonder why I need to add routes to my ubuntu, but iPhone works as is?!

Any clues on where to dig and fix the problem are appreciated!

I did setup port forward as in https://tailscale.com/kb/1019/subnets/?tab=linux and started as https://tailscale.com/kb/1019/subnets/?tab=linux and it worked !

The only unanswered issue is ... why I need to add routes to my ubuntu, but iPhone works as is?!

@chudak
start tailscale with:

sudo tailscale up --accept-routes

otherwise, tailscale is behaving as designed as a point-to-point VPN and the endpoints can only see each other
