OpenVPN as a default gateway

poldas · Jul 6, 2016, 8:56 AM

Hi,

I have OpenVPN server as a tun behind NAT.

LAN/WAN interface 192.168.101.250 (router is gateway - 192.168.101.1)
IPv4 Tunnel Network 192.168.44.0/24

I checked "Force all client generated traffic through the tunnel"

Client route table has second default gateway

Network Dest. Netmask Gateway Interface Metric
0.0.0.0 128.0.0.0 192.168.44.5 192.168.44.6 20

But trafic doesn't get to the Internet via OpenVPN…

tracert 8.8.8.8
192.168.44.1
192.168.101.1 - this is last hop

Do you have any idea what is wrong?

well, pfSense probably hasn't created NAT rules for the vpn subnet.

you could manually add them
or

you could assign an interface to your openvpn: i believe pfSense will add NAT automagically then (don't shoot me if i'm mistaken)
