I need to connect to my own server that runs Linux Mint. After installing Tailscale on both PCs (client and server) I can succesfully ping the server from client, but I'm unable to traceroute it. Viceversa, from server to client everything is working smooth. I tried checking firewalls on the server, but I'm unable to find anything that may block the connection. I stopped the ufw service (that was anyway already inactive), allowed anything in and out using these iptables commands:

iptables -P INPUT ACCEPT
iptables -P OUTPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -F

I have no idea what may prevent the connection.
