OpenVPN tunnel between pfsense and Amazon EC2 Softether Server

Post by deeztek » Sun Oct 22, 2017 9:22 pm

I'm trying to get an OpenVPN tunnel to work between pfsense and a Amazon EC2 instance running SoftEther VPN server.

I was able to connect pfsense as a client to the SoftEther VPN server at Amazon. The connection is established and an IP address is assigned. However, I cannot get any traffic between the two networks. Ping or traceroute does not work from either side.

I have added a route on the pfsense side to use the OpenVPN interface as the gateway to the amazon subnet. I have checked the firewall rules and still no dice.

Has anyone succeeded in getting a configuration like this to work? I know that I cannot setup a LAN to LAN bridge without SecureNAT because according to my understanding you cannot enable promiscuous mode on an Amazon instance, so I'm forced to use SecureNAT on the SoftEther server.

I would appreciate some insight on this.

Thanks

Can you ping to SecureNAT virtual host?

No, I can't ping the virtual host or any virtual addresses either.

Could you try to L2 mode OpenVPN?
