Dear All,

Would you please tell me what is the limit of the remote access VPN users connected simultaneously on a 2800 router with Advanced IP Services IOS?

Thanks in advance!

I have this problem too.

So,

For SSL VPN it is clear, but for Easy VPN the only limitation should be the IPSec VPN throughput:

The Cisco 2800 Series Module (AIM-VPN/SSL-2) can provide hardware-based IPSec encryption services of 30 and 90 Mbps in the Cisco 2801, 35 and 100 Mbps in the Cisco 2811, 90 and 125 Mbps in the Cisco 2821, and 100 and 150 Mbps in the Cisco 2851 (IPSec IMIX and 1400-byte packets).

Throughput is influenced by the type and capacity of the WAN connection and the average packet size.

Cisco has published design guides which also provide detailed analysis of various factors that impact VPN throughput, although test results are not broken down by specific 2800 router model.
