Hey, guess what Comcast Business routers are REALLY BAD at!

Apple Filing Protocol!

Guess what Time Machine uses!

Apple Filing Protocol!

Guess what giving a time machine backup server a fixed IP address makes the Comcast Business router insist upon trying to handle!

Apple Filing Protocol!

Guess what doesn't actually need and shouldn't get a fixed IP address after all maybe!

yeah.

Backups have been bringing the Murknet to its knees, and now I finally know why.

I hate to be a *snob* here, but typically ISP supplied routers are a bit... well shit. Totally worth doing the homework and getting a well regarded consumer router with alternate firmware.

That said, I lucked out with mine and my router *isn't* shit. I'd trade it for something like an edgerouter and a threepack of ubiquiti APs in a heartbeat tho.

Also, wouldn't you get name resolution through... what ever apple calls their mdns implimentation this week?

Well, of course they are. We have smarter hardware on the inside.

But we don't have our Class C anymore - we had to give it up when we moved. We have a tiny block of six fixed (real) IP addresses, and the comcast gateway/router has to be the router for those. (And has an IP in that range, permanently assigned.) And it really wants to do standard sorts of IP routing within that IP block.

So to get to a fixed-IP real-IP backup server (which I thought would be handy because Reasons that were ... either wrong or simply never got around to being tested, which is about the same thing), it has to go through the router/gateway.

Making the backup server rely solely on AFP for name resolution and have a dynamically-assigned IP (and therefore be inside our NAT wall, and never touched by the Comcast router) stopped all of that at once.

Oh right, now I remember, I wanted the ability to ssh and vnc in to that server from off-site. That's why I gave it a real (fixed) IP. I think I did that... maybe... once. Yeah, testing it.
