  Hello managers,

  I have the following net configuration:


     -------- ethernet --------
     | remh |------------------| remr | remote.net (in the 192.168 .. range)
     -------- --------
                                 |
                                 v

                                ISDN ppp link
               
                                 ^
                                 |
    --------- --------- -------- ethernet -
    | loch1 |-----| loch2 |----| locr |------------------ | local.net class B
    --------- --------- -------- -

  remr and locr work as router for the two nets and have both two interfaces
  (remr: pppremr and ethremr and locr: ppplocr and ethlocr).
  locr is a AXP 3000/300LX with isdn interface and the x25 distribution which
  includes isdnppp. The interface is automatically created during isdnstart.

  Here my problem:
  
     On locr there exist static route for the remote.net over the ppp link.
     I can ping/telnet to remh remr from locr and everything works as
     expected.

     On loch2 (or any host on local.net) there exist a route to ppplocr and I
     can ping/telnet to this. Also on this hosts exist a route for remote.net
     over this ppplocr interface
  
       b u t

     I can't ping or telnet any machine on the remote.net from other hosts
     but locr on the local.net.

 What did I missed?


I would be greatful for any advice.
