Hi there

I'm running an openvpn server with a /24 netmask for available IP client
addresses. We're still under 100 clients so this hasn't become an issue
yet, but I just noticed that a Windows client was saying it got it's
openvpn IP client address from a DHCP server running on the .254 address...

The server is actually set up to use the .1 address (ie "ifconfig
x.y.z.1 255.255.255.0"), so as far as I'm concerned, the .254 address is
available for a client. But the last thing I want is a client getting
that address and suddenly unicast DHCP queries start failing (because
they're hitting a client instead of a server)

I know the is  "DHCP emulation" - which could mean this is all
smoke-n-mirrors and doesn't actually have any negative effect  - but I
thought I'd ask. But I would also ask why it couldn't have declared
itself to be the .1 address - as that is internally consistent?

Thanks
