Hi Jay! Thank you! I'll definitely take a look at those cookbooks but, I already tried Havana (Cloud Archive) with OVS 1.11.0, same poor results.
Also, my previous region based on Grizzly / Quantum / GRE, worked perfectly for months (except with MTU = 1400) and, Havana is somehow different. Thanks!
