• Hi

    i want to run a GRE Tunnel from pfSense (2.2.6) to a Cisco IOS Router.
    The config on the Cisco router which currently runs the GRE tunnel looks like this:

    interface Loopback0
    no ip address
    ipv6 address 2001:1Axx:xxxx::1/128
    interface Tunnel0
    description IPv6-Uplink
    no ip address
    ipv6 enable
    ipv6 tcp adjust-mss 1424
    tunnel source GigabitEthernet0/0
    tunnel destination x.x.x.x

    what are the steps on pfsense to run this configuration ?

    feedback very much appreciated
