Determining allowable concurrent connections

[christopher_hall]

Greetings,

We have a PIX 501 and I'm in the process of replacing it with a ASA5505. We're currently using the 501 for a site-to-site vpn for disaster recovery purposes and I'm trying to verify the number of concurrent connections we can have.

Anyone have any thoughts?

Thanks,

Chris
