[pfSense Support] whats the difference between the Proxy arp and other VIP's?

[Simon O'Sullivan]

And in what cases should each of these virtual IP’s be used?   I have been mucking around with a multi wan subnets setup – it seems to be quite a common thread on the mailing list. If I could get some definitive answers I would be happy to write a small howto…   Thanks very much, Simon.
