I have installed tailscale on my Proxmox VE 7.3-4 host.
It is running but not replying to any ping requests and I cannot connect via SSH over the VPN network.
Syslog shows that ping requests are coming from the tailscale source PC and are directed at the correct tailscale target address.
I can ping and connect via SSH normally from the LAN.
Could this be some sort of firewall problem with the Proxmox host?
I am not having any problems with other servers, including a Synology NAS.
 
It seems that Proxmox firewall was letting requests in (as seen in journal) but was was not letting any replies out. I do not really understand the details of iptables but I seem to have gotten it working.

I may have done too much or not enough, but in Proxmox firewall console I added two new rules, one with direction IN and the other with direction OUT.
Code: 
Action= ACCEPT
Source =100.64.0.0/10
Destination=100.64.0.0/10
