Hm? devel-coLinux-20080302 should stop the increasing. There the
automatic generated mac is stored in registry. Exist this key?

# Automatic generated MAC, monitor number 'M', network device index 'X'
[HKEY_CURRENT_USER\Software\coLinux\monitor\M\ethX]
"mac"="00:ff:XX:XX:XX:XX"

Plesae start "colinux-daemon -v 3 -k ..." and watch for messages about
MAC. Should say "read" from registry key.

Configure a unique MAC for eth1, example:
eth1=pcap-bridge,WINLAN,02:00:00:00:00:03

You needs to remove entries from z25_persistent-net.rules ones after
running older versions again.
