      I want to construct a GRE Tunnel between a branch office (BO) and a Head office.(HO)
      The branch offices have a variety of equipment that we dont want to replace just yet.
      Internet access egresses the BO locally via an ISP (adsl / broadband/ fibre etc)
      the HO has 250mb fibre and a Cisco ASA doing the PPoE.

      Knowning now that pfsense wont tunnel through an ASA but only use transport and that both endpoints need a public IP I am in a dilema.

      I have 6 public IP addresses and I want to use one to terminate the GRE tunnels.
      Can I put pfsense at the edge and have it dial the PPoE connection and also route those extra IP addresses and handle a GRE tunnel from downstream cisco devices?

      If that wont work can i put in 2 pfsense hardware appliances one for the HO and one from the BO do to the tunnel?

      thanks for your help people..
