Has anybody used the STUN functionality of the Acme SD? I posed the following questions to our SE and engineer, but if anybody has actual experience with it I'd be curious to know how it works. -Does it work? J -Re: performance, is STUN less costly than a very short registration refresh rate (<30 seconds)? Some impact on performance of a fully loaded SD 4000 would be appreciated. -Is it a better solution than their hosted NAT traversal?
