multiple crypto accelerator cards in one FreeBSD box

[sekchye goh]

Hi there!
 we are thinking of  deploying a IPSEC VPN concentrator using multiple PCI bus
version VPN1401 cards  in a FreeBSD box using hifn support..
 From the technical specs in Soekris website
http://www.soekris.com/vpn1401.htm,
each card can support 24 to 70 connections.  The question is if we
put 3 VPN1401 cards in a single box, does this mean the FreeBSD box can support
3 x (24 to 70) IPSEC connections ?

Thanks in advance for the clarification and advice!

Best regards
