Exit node not working - Operation time out

SUPPORT QUESTIONS
1

Hi,

I want to use Tailscale Exit Node, I was able to set it up correctly using:
sudo tailscale up --advertise-exit-node --advertise-routes=10.x.x.x/24

Then I had some issues with DNS resolution, which I fixed by enabling MagicDNS:

❯ nslookup pidirdam
Server: 100.100.100.100
Address: 100.100.100.100#53

Now when I do a simple curl to google.com, this is what I get:

❯ curl https://google.com -vvv
** Trying 142.250.72.238…*
** TCP_NODELAY set*
** Trying 2607:f8b0:4007:817::200e…*
** TCP_NODELAY set*
** Connection failed*
** connect to 142.250.72.238 port 443 failed: Operation timed out*
** Connection failed*
** connect to 2607:f8b0:4007:817::200e port 443 failed: Operation timed out*
** Failed to connect to google port 443: Operation timed out*
** Closing connection 0*
curl: (7) Failed to connect to google port 443: Operation timed out

Any idea on what I did wrong?

Thank you
