Migration from Monowall to PFSense
-
(Sorry about my english !)
I was user of Monowall and I have an OpenVPN Tunnel between 2 offices.
I don't know the config of the server office, but my client OpenVPN config look's like this:<if>tap1</if>
<cport>5001</cport>
<type>tap</type>
<proto>udp</proto>
<sport>1194</sport>
<ver>2</ver>
<saddr>xxxxxxxxxxxxx</saddr>
<descr>VPN</descr>
<ca_cert>XXX</ca_cert>
<cli_cert>XXX</cli_cert>
<cli_key>XXX</cli_key>
<crypto>BF-CBC</crypto>That configuration gives me an ip like 192.168.5.4. My LAN IP is 172.16.1.0/24. This, merged with a static route saing that all that want to go to 192.168.2.0/24 (the other office IPs) passes through 192.168.5.1 (the gateway of the subnet where openVPN sends me inn), works for me.
PFSense doesnt create TAP interface, so i cannot create the route. I cannot ping 192.168.5.1 … I cannot do anything.
If I see the logs ... i understand that im connected:
Somebody can help me ?
Tnx a lot.

The errors you post show that one end is using TUN and one TAP - from the openvpn man page:
You cannot mix them, as they represent different underlying protocols.
If I understand it correctly, TUN devices are for routing and TAP devices for bridging. As you want to route then you want to use the TUN device at both ends.

Ok,
but it seems that pfsense takes TUN as default.
Monowall had a combobox to select between TUN or TAP … how can i change this into pfsense ? -
Don't know I'm afraid, I'm still fairly new to pfSense myself :)
