Jup, I see.

I've got an Apple LocalTalk PC Card and -hey!- there's a driver out there! Thanks to Bradford W. Johnson <johns393@maroon.tc.umn.edu> for finding and eliminating a routing-related bug in his driver!!
Some information to my configuration, I use netatalk 1.4b2 with asuns afpd, Kernel 2.0.34 and libc 5.4.23.

This is my net:

          +-------+ +-------+
----------+ leela +---------------+ tycho +-----------
eth1 +-------+ eth0 eth0 +---+---+ eth1
                                      |
                                      | ltalk0
                                      |

Anything missed?
My atalkd.conf's looks like this:

[hostname: tycho]
ltalk0 -seed -phase 1 -net 125 -addr 125.1 -zone "Local"
eth0 -seed -phase 2 -net 100-120 -addr 100.1 -zone "Ether"
eth1 -seed -phase 2 -net 130-140 -addr 130.1 -zone "Ether"

[hostname: leela]
eth0 -seed -phase 2 -net 100-120 -addr 101.1 -zone "Ether"
eth1 -seed -phase 2 -net 150-160 -addr 150.1 -zone "Ether"

Some Output of nbplkup and aecho:

----159.130 AEP Statistics----
3 packets sent, 3 packets received, 0% packet loss

My Questions:

- Why can't I reach LocalTalk devices from any other part of the net?
  (Neither with nbplkup nor with aecho)
- Why does PM7500 not show up in nbplkup from tycho?
- Are there any fixes for this?

Thank you for taking the time to read this, but I think, this maybe serious...

:wq! PoC
