这是我目前在FreeBSD 11.1-RELEASE上的pf.conf 。 它允许来自OpenVPN / UDP和SSH的传入连接，并允许private / vpnnetworking上的所有内容（分别为vtnet1和tun0 ）。 麻烦的是，我无法通过ipv6连接到OpenVPN或SSH。 如果我观察openvpn日志或在SSH上使用-v ，则会看到IPv6地址超时，然后下降到IPv4。
block all # allow all from host itself pass out inet all keep state pass out inet6 all keep state # allow all from private pass in quick on vtnet1 inet from any to any keep state # openvpn pass in quick proto udp to vtnet0 port openvpn keep state pass in quick on tun0 inet from any to any keep state # ssh pass in quick proto tcp to vtnet0 port ssh flags S/SA keep state
我试图改变我的configuration到以下允许IPv6：
block all # allow all from host itself pass out inet all keep state pass out inet6 all keep state # allow all from private pass in quick on vtnet1 inet from any to any keep state # openvpn pass in quick inet proto udp to vtnet0 port openvpn keep state pass in quick inet6 proto udp to vtnet0 port openvpn keep state pass in quick on tun0 inet from any to any keep state # ssh pass in quick inet proto tcp to vtnet0 port ssh flags S/SA keep state pass in quick inet6 proto tcp to vtnet0 port ssh flags S/SA keep state
但是我仍然无法build立IPv6连接。
