I'm trying to get an OpenVPN tunnel going on pfSense 1.2.3-RELEASE running on embedded routers.
I have a local LAN 10.34.43.0/254. The remote LAN is 10.200.1.0/24. The local pfSense is configured as the client, and the remote is configured as the server.
My OpenVPN tunnel is using the IP range 10.99.89.0/24 internally. There are also some additional LANs on the remote side routed through the tunnel, but the issue is not with those since my connectivity fails before that point in the chain.
The tunnel comes up fine and the logs look healthy. What I find is this:-
- I can ping and telnet to the remote LAN and the additional remote LANs from the local pfSense box's shell.
- I cannot ping or telnet to any remote LANs from the local network.
- I cannot ping or telnet to the local network from the remote LAN or the remote pfSense box's shell.
- If I tcpdump the tun interfaces on both sides and ping from the local LAN, I see the packets hit the tunnel locally, but they do not appear on the remote side (nor do they appear on the remote LAN interface if I tcpdump that).
- If I tcpdump the tun interfaces on both sides and ping from the local pfSense shell, I see the packets hit the tunnel locally, and exit the remote side. I can also tcpdump the remote LAN interface and see them pass there too.
- If I tcpdump the tun interfaces on both sides and ping from the remote pfSense shell, I see the packets hit the remote tun but they do not emerge from the local one.
Here is the config file the remote side is using:-
#user nobody #group nobody daemon keepalive 10 60 ping-timer-rem persist-tun persist-key dev tun proto udp cipher BF-CBC up /etc/rc.filter_configure down /etc/rc.filter_configure server 10.99.89.0 255.255.255.0 client-config-dir /var/etc/openvpn_csc push "route 10.200.1.0 255.255.255.0" lport <port> route 10.34.43.0 255.255.255.0 ca /var/etc/openvpn_server0.ca cert /var/etc/openvpn_server0.cert key /var/etc/openvpn_server0.key dh /var/etc/openvpn_server0.dh comp-lzo push "route 18.104.22.168 255.255.255.224" push "route 22.214.171.124 255.255.255.224" push "route 126.96.36.199 255.255.255.224" push "route 188.8.131.52 255.255.255.240" push "route 192.168.1.16 255.255.255.240" push "route 192.168.2.16 255.255.255.240"
Here is the local config:-
writepid /var/run/openvpn_client0.pid #user nobody #group nobody daemon keepalive 10 60 ping-timer-rem persist-tun persist-key dev tun proto udp cipher BF-CBC up /etc/rc.filter_configure down /etc/rc.filter_configure remote <host> <port> client lport 1194 ifconfig 10.99.89.2 10.99.89.1 ca /var/etc/openvpn_client0.ca cert /var/etc/openvpn_client0.cert key /var/etc/openvpn_client0.key comp-lzo
You can see the relevant parts of the routing tables extracted from pfSense here http://pastie.org/5365800
The local firewall permits all ICMP from the LAN, and my PC is allowed everything to anywhere. The remote firewall treats its LAN as trusted and permits all traffic on that interface.
Can anyone suggest why this is not working, and what I could try next?
