Thanks for the reply. Ok, I can see how I can generate some IDs, but I first 
want to make sure i have all of the information I need.

When I run conntrack, I only see one protocol number. I think it is a layer4 
protocol (tcp vs udp). If I'm not seeing an l3proto in my output, why might 
that be?

udp      17 12 src=10.10.201.2 dst=204.174.64.1 sport=54475 dport=53 
src=204.174.64.1 dst=209.53.156.2 sport=53 dport=54475 use=1 mark=0
tcp      6 420332 ESTABLISHED src=10.10.100.3 dst=10.10.1.22 sport=1356 
dport=5432 src=10.10.1.22 dst=10.10.100.3 sport=5432 dport=1356 [ASSURED] 
use=1 mark=0
