Setting manual ARP entries for NATs

If your recently created manual NAT is not working, maybe you need to create manually proxy ARP entries.

To do so, edit the file $FWDIR/conf/local.arp (or in VSX environments $FWDIR/CTX/CTX000<VSID>/conf/local.arp)

The contents should look like this:

192.168.10.100 00:1C:7F:82:01:FE
