4636.0. "packetforwarding in Digital Unix:SLIP ?" by TLAV01::CHENSAK () Wed Apr 23 1997 13:36

    I setup 2 Digital Unix (v3.2) to do the SLIP. One is Dial-in & another
    one is dial-out. I can setup it successfully ,i.e, I can ping remote
    host of the another side ,but I can't ping its own sl0 local interface.
    And this problem also causes another problem, because the customer want
    to let their small LAN clients to access to the other remote site, I
    config the tu0 network interface and run routed (at the Dial-out unix
    machine) , the PC on the small LAN that connect to the Dial-out can't
    ping the sl0 interface and remote SLIP machine 's IP. Do I have to
    modify the kernel ,like other unix ,that must modify the kernel to let
    it packetforwarding ?  How to solve this problem , please share with
    us.
    
            LAN 10.1.1.0  (subnet 255.255.255.0)
                          +---+   sl0 10.1.2.2      sl0 10.1.2.1 +---+
                  ------- |   |    ---------------------         |   |
                       Dial-out SLIP                           Dial-In SLIP
                      10.1.1.1 ,tu0
    the PC in LAN ,set the gatway to 10.1.1.1 

on Digital UNIX, iprsetup is what turns on routing

    Thanks for your help, now my PC in small LAN could ping the sl0
    interface of the dial-out SLIP, but still can't ping the sl0 interface of 
    the remote dial-in SLIP. Please help how to solve this problem.
