From kubernetes can tailscale ping but not ping

Hi, I have problem connecting a pod inside Kuberentes with a server in my PC, I can ping from my pc to Kubernetes but not from Kubernetes to my PC. I have used the image Tailscale/tailscale:latest, I execute tail scaled --tun=userspace-networking and capabilities NET_ADMIN and NET_RAW. And then the command Tailscale up with the authkey. From the control panel I see my two machines, the PC and the pod inside Kuberentes with status connected. If i tailscale ping from the pod to my pc, i receive the pong via and Endpoint, if i ping that endpoint it respond correctly, but i cannot do a curl request. Any idea on where there could be the problem?
If i ping and curl form another pc it works fine
