Sounds good.
Wrt to the problem statement: Seems your node takes a long time propagating changes to the gossip network. That might be solved with clearnet, but I’m not sure. When Tor works, it should not take longer than 15 Minutes. What might solve for that: Find some well connected nodes (bcash, wallet of satoshi, c-otto or others) and add them as peers. That helps receiving and sending gossip updates more frequently.
I’ve also seen this happening to nodes with few channels. I know, easier said than done, but adding more channels helps speeding up, too.

here is the original guide from Osito and myself. It’s also updated for achieving IPv6 listening. I can’t edit the guide here anymore, so need to deal with an external link.

fewer than 5% of nodes out there communicate over IPv6, I don’t think it’s a critical element, at least not now. But on the DynDNS list, the guide above provides a list of DynDNS providers. duckdns.org, my favorite one, doesn’t offer IPv6 DNS lookup

for the most sophisticated setup, you might consider adding your own VPS to allow VPN tunneling. The guide can be found here. This is more for rather serious node runners, who are in for the long and anonymous way. With this, adding your own domain name would also be possible, but not necessary, since you’ll have a static IP anyway
Hope this helps
