Possible 01-netcfg.yaml conlicts?

    So, I had tried to setup Static IPs, since my router only allows IPv4 Leases it seems,
    The following is my 01-netcfg.yaml file, modified from each server setup to TRY and use Static IPv6
    as well as the eno1 output from ifconfig from each
    The issue is, sometimes the DHCP Lease doesn't take place, and it causes communication issues between my servers.
    I add the extra user for each of the ::7 and the ::9 ending ones during setup... but as I said, the DHCP lease doesn't always seem to take place, so indeed you might ascertain that this could be quite frustrating to a novice.

    Maybe I'm just missing something, or I really should invest in a better router and put my modem/router combo into just modem bridge mode?

    Any suggestions in that case for an inexpensive, and effective router. Possibly one that supports DD-WRT/OpenWRT, or a very exstensive default
