Hello,
I'm trying to set up a "road warrior" VPN for my company.
We have a pfSense firewall (FreeBSD-based) which we use for all our VPN stuff.
The device is configured like so:
- 10.40.2.1/16 on the LAN interface
- IPsec tunnel VPN with remote network 192.168.40.100/24, with NAT 1:1 from 172.16.0.0/16 to 10.40.0.0/16 (this is with a SaaS company that won't change their setup unless strictly necessary)
- The OpenVPN configuration file at the end of this email
- Bridge between the LAN interface and the OpenVPN (ovpns1) interface
The issue is that everything can be reached from the "road warrior" clients normally, except for the firewall (10.40.2.1) and hosts over the IPsec VPN (which is the entire reason I'm using TAP instead of TUN: I need to keep the road warrior clients in the same network that can access the IPsec VPN).
The weird thing is that the firewall can be pinged and answers (but I suspect that's an OpenVPN thing), but I cannot reach its web configuration interface or connect with SSH. Please note that this is not a binding issue nor a firewall issue, the web interface binds on 0:443 and the firewall is temporarily set to allow everything to pass.
Right now I have a second "road warrior" VPN access, using IPsec, which works with the web interface but still doesn't work with the other IPsec VPN. I would really like to use OpenVPN because IPsec looks pretty hackish to me, especially how it is implemented on pfSense/FreeBSD.
Best regards,
Riccardo Paolo Bestetti
