Sorry, could we get that one more time with a little different flag:

Code: Select all

iptables -L -n

This all looks ok, one other possibility would be that Network Analyzer cannot access what it needs to in the netflow data. Is SELinux enabled?

Code: Select all

getenforce
And, do you have any errors in the apache error log after trying to access this page?

Code: Select all

Hey guys, thank you very much for your help. It turns out it was a timestamp issue on the exported flows. I noticed the captures were getting a timestamp of 1969-12-31 18:00:00.000. I added the necessary timestamp commands on the cisco gear and now it's working.

Thanks again.

Fantasic, glad you figured it out! Also thanks for the note, I didn't even know it was possible to change the flow timestamp at the router level! Locking it up for now. If you need it unlocked let me know.
