      Hello,

      I'm not sure whether this is a pfSense or a FreeBSD bug (or even if it is a bug), but here i go:

      I've a setup where my pfSense 2.1-BETA1-i386-20121228-1654 lies behing my ISP's router. To be able to send WOL packets over internet, i've entered static ARP entries in pfsense via the shellcmd plugin:

      
      arp -s 192.168.100.111 xx:xx:xx:xx:xx:xx
      arp -s 192.168.100.120 yy:yy:yy:yy:yy:yy
      
      

      I've double checked the -s parameter which stays for "static".
      But after 5 minutes these ARP entries get cleared.

      I've to use

      
      arp -S 192.168.100.111 xx:xx:xx:xx:xx:xx
      
      

      for ARP entries to stay.
      I'm pretty sure this ain't the biggest bug report ever, but at least maybe it will save a bit time for Wake On Lan Wan DIY guys.
      Btw, i've NATTED some of my ISP's router ports to port 7 & 9 of my pfSense in order for WOL packets to be transmitted, and it works great.

      Cheers.

        Refer to the FreeBSD ARP (arp) manual page.  Particularly the -S option.  I think the answer is there.

        Capability for creating static ARP table entries from DHCP static mappings is available in Services: DHCP Server.

        See attached document for additional WoL configuration details.  (remove the .jpg extension)
