UPDATE: Got my Omni today!When I first started it up, it wouldn't go online so i tried flashing back to my TP-Link C2600 stock firmware when it went online but blocked ALL my outbound network traffic.

So i did a quick check, and my stock firmware isn't supported.
At that point, i flashed back to OpenWRT, restored my configuration, and did some poking around... long story short,
do not disable IPv6 DHCP! It appears the Omni needs it even though it picks up a IPv4 address.
Whats interesting is that while i was on my stock firmware, the Omni broadcasted its MAC for all the entries in the ARP table. Im assuming this is how the Omni is configured so that it can inspect the network traffic. While on OpenWRT, I do not see the same behavior.... but my network traffic does get out.
At this point I'm not sure the Omni is actually collecting my network traffic.
Id be glad to dig into this more but its a bit late and i need to get some Z
zzzs in before work.
