Is it possible to add entities to ARP table manually?

Hey All

Is it possible to add entities to ARP table manually in pfSense 2.0?

sure why not?

[2.0-BETA5][admin@pfsense.local.lan]/root(4): arp
usage: arp [-n] [-i interface] hostname
      arp [-n] [-i interface] -a
      arp -d hostname [pub]
      arp -d [-i interface] -a
      arp -s hostname ether_addr [temp] [reject | blackhole] [pub [only]]
      arp -S hostname ether_addr [temp] [reject | blackhole] [pub [only]]
      arp -f filename

-s hostname ether_addr
    Create an ARP entry for the host called hostname with the Ethernet address ether_addr.
            The Ethernet address is given as six hex
    bytes separated by colons.  The entry will be permanent unless
    the word temp is given in the command.  If the word pub is given,
    the entry will be published''; i.e., this system will act as an     ARP server, responding to requests for hostname even though the     host address is not its own.  In this case the ether_addr can be     given as auto in which case the interfaces on this host will be     examined, and if one of them is found to occupy the same subnet,     its Ethernet address will be used.  If the only keyword is also     specified, this will create a published (proxy only)'' entry.
    This type of entry is created automatically if arp detects that a
    routing table entry for hostname already exists.

-S hostname ether_addr
    Is just like -s except any existing ARP entry for this host will
    be deleted first.
