Can I Route all traffic through an IPSec VPN?



  • I work at a High School district with 2 campuses A & B.  Those 2 campuses are linked with a high speed WAN link and share 1 Fiber Internet connection that comes in at campus A.  We're using PfSense as the firewall for that connection and it's been working great.  We now have a small auxillary building in town we need on the network.  We got cable modem service put in and put in a pfsense box there and established an IPSec VPN tunnel between that cable modem and our primary fiber internet connection.  Now that building has access to all LAN resources but we need to take it a step further. 
    Since we have a commercial content filter installed that sits in bridge mode between the LAN and Firewall at the primary campus, we would like to direct the auxillary building to go through it.  Is this possible at all?  We don't want to have to maintain 2 content filters if possible but have to provide content filtering for this facility.
    If we could just have the auxillary buildings firewall route all traffic to the primary campus LAN switch that does routing it could take care of it but I don't know if that's possible.

    Thoughts?



  • I'm not sure w/ ipsec, but it is definitely possible via openvpn (ssl).

    hope this helps.
