    hello

    I successively implemented (i think) a VPN LAN to LAN connections between 2 sites, folowing this tutorial: http://www.ieee754.org/?p=17 .

    The connections was made over UDP port and i can ping machines from one site to other, every thing seems to work fine, however if i sniff the BOND interface using iptraf tool i dont see any UDP packets.

    Since VPN conections is based on UDP, shouldn’t i see the UDP packets traveling in the BOND interface? I have made a sftp file transfer between two sites, transferring the file very slowly from one site to other, however didn’t saw any UDP packets in the interface.

    Am i doing something wrong?

    Hi , you can see udp packets on physical interfaces , udp is the vpn carrier protocol, not the passenger protocol , which could also be different , like tcp
