Super smooth upgrade from 0.19.0 -> 0.20.0 and love the new UI I use Ansible to deploy Netmaker, so after updating everything to match the new variables and other file changes it was smooth sailing. Issue still present since 0.18.6 is needing to do

iptables -I FORWARD -i netmaker -j ACCEPT

on any Ingress nodes, otherwise certain traffic from Ext Clients won't work. Ext Client -> Ingress w/ Caddy server -> (Reverse Proxy) other node over NM network (fails, appears to times out)
