Limitations on site to site VPN connections using Cisco 837s and PIX
We have a number of remote sites with Cisco 837s installed, with IPSEC tunnels terminating on our PIX515E at Head Office.
We also have a number of site to site VPNs between some of the Cisco 837s.
As the number of connections is steadily growing, I wondered if anyone could give me an indication of the maximum number of connections I can have before we will start to see performance problems on this kit?
i.e. what are the limitations on number of site to site VPN connections on the Cisco 837?
And what are the limitations on number of VPN connections on the PIX515E?
Any advice or information that can be offered on the above would be appreciated.
