Your aren’t going to terminate the ssl connections  on
The firewall ??? what benefit would ssl accelerators provide.

We are planning something similar at the moment. My present thoughts are to use 
opteron processors on the vpn servers. And run pfsense on that hardware.

And then forget above ssl and ipsec accelerators. Let the core hardware do the 
work. The stats that I have seen make me seem to think that acceleration is 
just generally lots of cpu and good throughput

Just two cents worth don't know if it will help you but then again your replies 
might help me.

Well, here's what I know.  There are basically three chipsets that  
implement crytpo in hardware.  There are three drivers in FreeBSD  
that work with them: hifn(4), safe(4), and ubsec(4).

Of these, the hifn(4) driver seems to register to support many more  
modes of operation than the other two do, especially if you use the  
recent chipsets.  The current Soekris 1401 card uses the hifn 7955  
chip, so one would expect that most IPsec operations are  
accelerated.  However, the man page for the driver says this about  
the chip:

      Support for the 7955 and 7956 is incomplete; the asymmetric  
crypto facil-
      ities are to be added and the performance is suboptimal.

So everything is just confusing beyond belief now.  The cards using  
the ubsec(4) driver support async operations (eg, RSA needed for SSL  
accelaration).  So which card to choose depends on what your use for  
it will be.

Here are the links to the cards I am considering so far:

http://www.safenet-inc.com/products/accCards/safeXcel171.asp
http://www.gtgi.com/products_powercrypt5x.php
http://www.soekris.com/vpn1401.htm

I have need for both IPsec use on my pfSense box as well as SSL  
acceleration on my front-end web servers, so I may end up buying  
different cards for each purpose.  I guess it depends on price, even  
when using the company card. :-)

I suspect the Soekris will be great for IPsec workload.
