time capsule network incompatibility

I just found out (the "hard way") that time capsules do not work for time machine backup when they are configured for passthrough. (not distributing ip addresses via DHCP) They will appear to be fine with setup, but the backups will fail every time.

Just thought I'd pass that along. I was NOT expecting that to be an issue. But it took 30 minutes and tier 2 applecare to dig up that nugget. They don't appear to want to openly advertise that limitation.

Mine (simultaneous dual band v-7.5.2) is setup for passthrough of DHCP and works fine......it is assigned a fixed IP address and has been working since this time last year as currently configured in bridge mode.

fixed ip may be the missing ingredient then. apple does tend to fall back to "that doesn't work" or "that's an unsupported configuration" when you stump them on how to make something Just Work.

I set it up with a fixed IP once I realized that it wasn't going to be the xxx.xxx.xxx.1 device on the LAN and it wouldn't work well to have it jump around in the DHCP pool with all the other clients.....so I gave it a fixed IP outside the DHCP pool so there was no chance of inadvertent address conflict and it has "just worked" ever since. I have several network devices that I have assigned fixed IP addresses to -- network printers, wireless repeaters, and Network Attached Storage (NAS) drives each with their own range of fixed IP's within the LAN.

I like my printers to all fall within the next block of 10 addresses above the router, my NAS devices to fall within the next block of 10 above that, and each of the WiFi devices to have a major key number such as xxx.xxx.xxx.230, 240, 250......and I limit my DHCP pool to a smaller subset in the 170 to 195 range.

It's my total ignorance of the subject under discussion, of course, but that is the most incomprehensible post I've ever read, the Hal-ganbustein exchanges included. confused

That's only because it's "old-school" networking from back in the day.....like when we used to make our own null-modem serial cables from junk out of the drawer under the work bench! blush
