OpenVPN and IPSEC Passthrough Breaks access to local resources



  • Hi,

    I've setup two internal LAN networks on separate interfaces. VPN passthrough to a foreign site works from my client computer for both OpenVPN and IPSEC protocols but breaks access to the other local LAN network.

    If Client on 10.20.20.0/23  Network -> Then OpenVPN/IPSEC to foreign site -> No longer access 10.30.30/23 Network.
    If Client on 10.30.30.0/23 Network -> Then OpenVPN/IPSEC to foreign site -> No longer access 10.20.20.0/23 Network.

    I'm not sure if this is a NAT problem or a Routing problem but it seems odd that I would break connection to the other Local LAN network once VPNing to a foreign site.

    If I need to provide any more documentation please let me know.

    Thanks.

    It could either be routing/policy routing or firewall rules. But it's hard to say for sure with the info you gave.

    In the case you're talking about, is the VPN connection being handled by pfSense or by client software on the PC?

    What do your LAN rules look like? (screenshot would be sufficient, feel free to blur/block any IPs)

    What do your interface configurations look like? Do you have gateways selected from the drop-down on the interface config only for WAN-type interfaces?
