    Hi,

    I had a problem with my virtual tunnel here, since i couldnt make 2 separate
    networks from different location connected via tunnel i made with interface
    gif.

       net A ----------------fbsd A --------------------- fbsd B --------- net B
    1.1.1.0/24 203.50.166.76 202.53.167.77
    2.2.2.0/24
                                              |
    |
                                              |________tunnel gif________|
                                          3.3.3.1/30
    3.3.3.2/30

    On net A i have PC win2k 1.1.1.2
    On fbsd A i have 1.1.1.1 and 203.50.166.76

    On net B I have PC win2k 2.2.2.2
    On fbsd B I have 2.2.2.1 and 202.53.167.77

    I make the gif tunnel in freebsd A with :

    ----------------------------
    ifconfig gif create

    gifconfig gif0 203.50.166.76 202.53.167.77
    ifconfig gif0 inet 3.3.3.1 3.3.3.2 netmask 0xffffffff
    ipfw add 1 allow ip from any to any via gif0
    ----------------------------

    Than to reach the others networks :

    route add -net 2.2.2.0/24 3.3.3.2

    I configure freebsd B like freebsd A with opposite .

    But why I still couldn`t ping from pc A 1.1.1.2 to pc B 2.2.2.2
    Indeed.. I couldn`t ping from pc A 1.1.1.2 to the opposite gif tunnel Point
    to point in freebsd B 3.3.3.2

    Anybody could help,

    regards

    NB : I still dont touch the IPSEC and encrypted section ,since in the fbsd
    handbooks said to make an encrypted section i must have the 2 networks
    connected. Is this right?
