Yes. 

***2.2 kernels***
  # mknod -m 660 /dev/tap0 c 36 0

  And also add these lines to /etc/conf.modules:
   alias char-major-36 ethertap
   alias tap0 ethertap

***2.4 kernels***
  # mknod -m 660 /dev/tun c 10 200
        now it's a miscdev (major 10) and the minor 200 identifies the module

  And add these lines to /etc/conf.modules:
   alias char-major-10-200 tun
   alias tap0 tun

I dont know if all these lines are needed. It is still beta :) This way the
router runs until "Now run client" without errors.

I started simnode after the router said "Now run client". It's giving me
some device errors yet... Something related to the connect call of the
unixif interface.

Simhost gave me interface problem too.

Well, this was just one day work. :) There's more to come, I hope...

Ok, let's try it.
