 Net-flow data capture Hello, I'm trying to capture net-flow data on a vpn router 1811 to be exact. And I'm getting nothing "0" from this router. The code is 12.4. I called support and there saying it's our vpn concentrator is a cisco asa running 8.0(3) code. My team of engineer are blaming the remote router. I'm leaning towards the asa, b/c it's a vpn tunnel and that's were the traffic goes back to. Also, acl are permitting traffic, and firewalls are not blocking ports. Please Help, I really would like to hear your opinion. Thanks guys and gals. | ||

From my experience, traditional versions of Netflow do not support sending flows across an IPSec VPN when the VPN endpoint is generating the flows. Try researching flexible netflow. Flexible NetFlow - Cisco Systems __________________ There is no place like 127.0.0.1 BUT 209.62.5.3 is my 127.0.0.1 away from 127.0.0.1! | ||
