Route another subnet through ipsec tunnel



  • Hello All.

    I'm new to this forum and pfsense too.
    I would like your help configuring a routing rule on my running pfsense firewall.

    My configuration is

    Site A (headquarter)
    Firewall Zywall USG 110
    Lan 192.168.1.0/24

    Site B (cloud rdp server)
    Firewall Pfsense
    Lan 192.168.40.0/24

    Site C (remote office)
    Firewall Zywall USG20
    Lan 192.168.4.0/24

    There are 2 ipsec tunnel running correctly.
    Ipsec Site A to Site B
    Ipsec Site A to Site C

    I would like to reach site B from site C (and site C from site B) without configure a new ipsec vpn between them because in the future I will have more remote office.

    I already created some routing policies on Zywall for site A and C but I don't know how to tell Pfsense that traffic from 192.168.40.0/24 to 192.168.4.0/24 must go out trough Ipsec tunnel.

    Can anyone help me please?
    Thank you very much.
