Cisco 3925 VPN questions

[mistryj]

Hello,

Does anyone know what the maximum concurrent users you can have on a Cisco 3925 for :-

1) Site to Site VPN using IPSEC tunnels
2) GRE tunnels

If I have 90 users on a single GRE tunnel with 50mb Internet pipe using fat clients will this work ?

There's no limit on users. Bandwidth and latency may limit but that depends on the applications and the amount of data being pushed across the link.

As Jeff has correctly pointed out, there is no limit on the number of users when you do site to site VPN. This is true whether it is IPSec tunnels or GRE tunnels. So there is not any limit on number of users that will impact you.

The real question here is what will the performance be on a 3925 with a 50 mb connection and about 90 users. My guess is that it will be ok. But I do not have any hard numbers that would confirm this. It also depends on what the 3925 will be doing in addition to the tunnel traffic.
