Is it possible to add entities to ARP table manually?
Is it possible to add entities to ARP table manually in pfSense 2.0?
sure why not?
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 apublished (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.
