Re: [FW1] local.arp

[Robert A. Wallace <rob.wallace@theALLIEDgroup.com>]

I just read this article concerning local.arp www.geek-speak.net/fw1.
Drawbacks - local.arp does not consistently work under heavy traffic loads or
if you have 10 or more entries.
You could configure the proxy arp on the router.

Any thoughts!
