I’m new to VPN and was glad that ZeroTier was very easy to install and use. I connected several Windows PCs without any problem. But when I tried to connect to my Raspberry, every connection is rejected.
I found out, that the firewall (iptables) blocks the connection to the VPN. “
zerotier-cli info” shows me OFFLINE, as soon as I start the iptables rules. I attached rules at the beginning of the chain to accept every incoming and outgoing connection from the IP range of the VPN(10.147.x.0). And I accept every connection from the virtual ZT interface.
But in the end every attempt to connect runs though the chain and is rejected. I read several HowTos, but they are all regarding the forwarding of communication and using the Raspberry as a kind of gateway.
But I just want to establish a connection to the Raspberry like to a normal computer. Any ideas?
