Hey Pepole!!

    My name is Juda and i need to set up Tunnel
    From my Home Linux machine to my ISP Cisco Router
   =20
    i Do know how to set up simple ip-ip tunnel
    Here is the script i have build to set it up

insmod ipip
ip tunnel add neta mode ipip remote _REMOTE_ROUTER local =
_MY_LOCAL_INTERFACE
ip addr add __MY_TUNNEL_IP_ADDR dev neta
ip link set neta up
ip route add _FORIEGN NETWORK dev neta


well it's work great

i have set up on My Cisco using  tunnel protocol  ipip    (Also called =
protocol 4)
Network 192.168.1.0  =20
    Cisco Interface: 192.168.1.1
    Linux Interface: 192.168.1.2


And i was able to ping from the cisco to the Linux

My problem is that my ISP use a   Cisco implemented IP over IP =
encapsulation called NOS (KA9Q/NOS Compatiable) , also named protocol 94

i have made some debugs and with the tunnel i have set up below  my =
computer (192.168.1.2) able to ping to the Cisco Machine
But when the cisco send reply , my   machine send to the router     =
protocol unreachable

that means my linux box dont recognize the NOS protocol   , i have pass =
allmost the whole linux how to documents

grep "NOS" *    / grep "nos"   *   / grep "tunnel" *   =20
and i havent find any HowTo that talk about NOS   the only one was  =
AX25-HOWTO =20

and i have tried to use there example    but i am getting error
Destation on reachable
when i am tring to set up the route


Help will be apprechated
Sincer Juda(Love Linux) Barnes
