1. Is PIX 515E capable to send Netflow packets?

2. Is Catalyst 3750 capable to send Netflow packets?

3. I have 3845 router but - If monitoring ouside interface - I do not see a real source of the packets (because of NAT). If i am monitoring inside interface - Netflow statistics is not clear to me - I think I do not see trafic that goes through IPSec VTY. Can some one advice me a kind of NetFlow collection best practices?

Thank you.

2. No, not according to this:

3. Here's a whitepaper that might help:
