https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D227086 --- Comment #2 from Marek <zillion1@o2.pl> --- Hi Eugene, I can test old revision only (home server "in production") :) Some more outputs from working/current configuration: # ifconfig tun0 tun0: flags=3D8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1500 options=3D80000<LINKSTATE> inet 10.20.20.1 --> 10.20.20.2 netmask 0xffffff00 groups: tun Opened by PID 789 # ifconfig tun1 tun1: flags=3D8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1500 options=3D80000<LINKSTATE> inet 10.20.20.10 --> 10.20.20.1 netmask 0xffffff00 groups: tun Opened by PID 24835 # netstat -rn Routing tables Internet: Destination Gateway Flags Netif Expire default 11.22.33.44 UGS igb1 10.20.20.0/24 10.20.20.2 UGS tun0 10.20.20.1 link#9 UH tun1 10.20.20.2 link#5 UH tun0 10.20.20.10 link#9 UHS lo0 11.22.33.0/22 link#2 U igb1 11.22.33.44 link#2 UHS lo0 127.0.0.1 link#3 UH lo0 192.168.0.0/24 link#1 U igb0 192.168.0.1 link#1 UHS lo0 192.168.8.0/24 link#4 U ue0 192.168.8.100 link#4 UHS lo0 # ps ax | grep openvpn 789 - Ss 1:01,30 /usr/local/sbin/openvpn --cd /usr/local/etc/openv= pn --daemon openvpn --config /usr/local/etc/openvpn/server.conf --writepid /var/run/openvpn.pid 24835 - Ss 0:06,92 /usr/local/sbin/openvpn --cd /usr/local/etc/openv= pn --daemon openvpn_client --config /usr/local/etc/openvpn/client.conf --write= pid /var/run/openvpn_client.pid My home host is "master" OpenVPN server for about 20 other remote family clients. They're connecting to the server without any problems (after install world there was no probem with them too). The OpenVPN client (tun1) on master host is configured to listen some servi= ces like mail, www, and couple of others. Additionaly I have failover server in remote localization, so in case connectivity problems to master host, the failover takes over with 10.20.20= .1 IP address. Clients reconnect after some timeout to the failover. The failover is not FreeBSD based system, and there's no services like mail, www, and so on, its task is to keep connectivity beetween other clients if = main host is temporarily down. To aviod unnecessary requests to the failover from clients, I created on ma= ster host the VPN client next to server with 10.20.20.10 IP address.
