So it depends. For example some legacy apple stuff had a bad DHCP implementation where it would try to hold onto an IP address it had before.

When there’s one DHCP server with a reserved ip it won’t assign that ip to the wrong device. (Unless you’re running some buggy software that takes your configuration as suggestions)

Where the advice to set it anyways comes from scenarios where that DHCP server goes down for long enough that everyone starts self assigning addresses. It’s a real hassle to find the correct system when that happens.

Kubuntu LTS is the same Day service and support to the following link unsubscribe.

Avoiding spam filters and ISP blocks are a common issue with self hosted email.

Ideally you’ll have a mature domain, dkim configured and an IP that’s not blacklisted on a network that allows email traffic.

OVH offers pretty cheap email hosting if you just want a turn key solution.

Otherwise if you want your home lab to work this way you may need to configure something akin to a forward proxy on a VPS to act as a gateway for your homelab.

This could be achieved using wireguard and iptables. By routing the email traffic to your homelab.

I forgot about an old install of tumbleweed and had thousands of packages that needed updating. To my shock it worked.

I watched a ocean of computers go dead on the floor because I couldn’t convince the sysadmin to do exactly that when pushing a major change.

But how do I integrate everything into Microsoft 365 with that snazzy OneDrive feature? /s

This has happened and taken a bunch of services down around the world.

Even that can’t be trusted these days. The computer can be configured to come back on and connect to the network.

This is why I’m only interested in laptops with removable batteries but it’s become rarer and rarer.

I’d suggest using OVH. https://help.ovhcloud.com/csm/en-ie-dns-dynhost?id=kb_article_view&sysparm_article=KB0051641

Depending on your country you may need to use ovh canada

Syncthing like others suggested is probably the way to go.

But if you want more options you can do a lot with WebDAV. https://www.digitalocean.com/community/tutorials/how-to-configure-webdav-access-with-apache-on-ubuntu-18-04

It’s possible that the app has been disabled on the Play store if the developer has failed to raise the SDK level. A bunch of apps have been delisted for that reason.

If you still have the purchase email you may be able to contact the developer about it.

Hey I just had another thought. Do you have your ISP provided router in bridge mode? That would help if you’re not using it for anything else.

If your lan devices only have a fe80, your clients are not receiving a proper router advertisement.

Which routes and firewall rules should I be checking?

Since the OPNsense device is getting a ipv6 address and is able to ping ipv6 devices on the internet.

It sounds like you don’t have ipv6 configured for the LAN. Try enabling “Assisted” mode.

https://docs.opnsense.org/manual/radvd.html

Confirm the ipv6 addresses your clients in the LAN are being assigned an ipv6 address within the scope of what your ISP is assigning.

If you are check default routes and firewall rules.

If you aren’t, investigate “router advertisement”.

I like that idea.

I’d suggest OVH or Digital Ocean.

If you think a DDoS attack is possible I’d suggest azure for that.

Sounds like an issue with your registrar more so than the domain authority?

Do you have any information to distinguish that?

Does anyone here know if they are the same entity?

This is probably a bit extreme. I think it has a way to tie into your phone’s calendar too.

But you could use redmine and create tickets and reoccuring tasks.

Using a whitelist in this manner with cloudflare may be challenging as this list can potentially change. They do have means to query it though. https://developers.cloudflare.com/api/operations/cloudflare-i-ps-cloudflare-ip-details Additionally, have you considered ipv6 support?

if you haven’t solved the problem yet, I would consider switching to Apache for your reverse proxy and using mod_remoteip.

Track the CF-Connecting-IP field instead of the IP address to get the client.
