Proxy ARP range does not show all usable IPs
When using a network range in proxy ARP, the various Address drop downs, like on firewall_nat_edit.php, that pre-fill the available VIPs do not pre-fill all of the IPs available in the specified PARP IP range. It only shows the network address.
Ticket #386. Add all possible proxy arp to the external ip when it is defined as network.
Ticket #386. Add all possible proxy arp to the external ip when it is defined as network even on outbound NAT.
Ticket #386. Add even the network address to the list of addresses on proxy arp vips to the naat out edit.
