For anyone who still monitors this site:

The Itus Shield has been updated on OpenWrt to support the 5.10 LTS kernel.  I am currently running the OpenWrt master branch on the Linux 5.15 kernel.
While OpenWrt only supports the (R)outer slot, my personal repo has re-enabled the (B)ridge and (G)ateway slots.  If anyone wants a custom image for those slots, or the commit to re-enable those slots for their own build, feel free to ask.

Other notables:

I have a working rust-lang implementation that I'm working to incorporate into OpenWrt's build system.  This allows for rust-lang packages, including Suricata 6, to be used.  

I have incorporated RAM Swap in my images along with zstd compression, which significantly increases the usable RAM footprint.

Additionally, OpenWrt master branch has moved to Firewall4, and can I can demonstrate full throughput through the WAN ports.  This is (surprisingly) the case even through Suricata 6, with almost no loss of speed even though it is inspecting the packets. This in through my local network BUT out the WAN port.
