Of course we believe you. :-)

It appears to be a problem with the version of pwlib that the snapshots are
compiled against.

Here is the output of the pwlib sample app called netif on my machine:
=====
Net Test Utility

The interface table has 6 entries
0 lo 127.0.0.1 255.0.0.0 00-00-00-00-00-00.
1 eth0 10.62.10.213 255.255.255.0 00-08-74-48-6D-47.
2 vif1.0 10.1.1.128 255.255.255.255 FE-FF-FF-FF-FF-FF.
3 vif1.0 10.1.1.128 255.255.255.255 FE-FF-FF-FF-FF-FF.
4 vif1.0 10.1.1.128 255.255.255.255 FE-FF-FF-FF-FF-FF.
5 vif1.0 10.1.1.128 255.255.255.255 FE-FF-FF-FF-FF-FF.

The route table has 5 entries
0 10.1.1.1 255.255.255.255 0.0.0.0 vif1.0 0.
1 10.62.10.0 255.255.255.0 0.0.0.0 eth0 0.
2 169.254.0.0 255.255.0.0 0.0.0.0 eth0 0.
3 0.0.0.0 0.0.0.0 10.62.10.7 eth0 0.
4 0.0.0.0 0.0.0.0 10.62.10.7 eth0 0.

Default gateway is 10.62.10.7

Gateway is on eth0
=====

vif1.0 obviously has four different IP addresses on my machine.

This is the last Changelog entry in the version of pwlib used in the
snapshots (as of right now):
=====
2006-02-23 01:31  csoutheren

	* include/ptbuildopts.h.in: Backport from head
=====

I've also read the source code to GetInterfaceTable in pwlib and this
output is exactly what I would expect, so if yours is working differently
you much have a different version.
