Static ARP entries do not stay

deajan

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)
