Hi Guys,

Does anyone have any real-world figures for the maximum number of IPSEC 
tunnels it is possible to run concurrently on an 1841 without the 
additional VPN/SSL AIM?

The following doc indicates 800 with the AIM:

Is 300 tunnels a reasonable figure?  Traffic to this headend would be 
exceptionally low (less than 1Mbps in either direction) from spoke sites 
but there are lots of them!
