Lightroom on a NAS & New Router

[fsa]

I have to replace a slowly failing router, and I store all of my photos on my Synology NAS.  If I re-establish all the exact same mappings to the NAS, will my catalogs still recognize those mappings, or will I have to somehow rebuild the catalog?

If you keep all the same mappings, LrC should be happy and work without any additional effort.

Thank you! I'll be setting up the router tonight, I hope, and running some tests.  I'm not deactivating the old router until I'm sure this thing works, though.

The router shouldn't have any effect on your NAS except maybe the internal IP address might change and even that you could just set up the same.

Thank you! My plan is to keep the same addressing, so as to mitigate any potential problems like that.

I've set up the new router with the same IP address as the old router, and I can't get to the NAS.  I can ping it, but I can't get to the web portal, nor can I find it using the Synology Assistant.  I even tried stopping the firewall, with no joy.

Any suggestions?

Did you set up the new router with the same lan network setup? It us not enough to just give it the same ip. Your LAN network needs to have the same subnet setup so that traffic can route to it. So if you had your old router setup with a lan subnet if for example 192.168.254.x with mask 255.255.255.0, your router would be at 192.168.254.1, and your nas would be somewhere like 182.268.254.110 or so (if you set it up with a static ip). Typically your router would be set up with a dhcp server that hands out ip addresses in a subset of the legal range of 2 to 254 (0 and 1 are reserved for broadcast and the router typically). If you just set up the nas with a n address that is not in a subnet the router handles, it won't be able to route traffic to the internet and won't react to broadcast traffic. It needs to be on the same subnet as your router is handling.

Yes, I did, and I finally - in the wee hours of the morning! - manage to get everyone talking. I did everything I could think of, and then rebooted the NAS. It kept spontaneously shutting down. I pulled each drive, blew out the box, reseated them and then powered up the NAS. It stabilized and was recognized. Desperate times call for desperate measures, I guess.  Thanks for taking the time to respond! I appreciate it.

Also, once I was able to see the NAS, all the mappings worked without any other tweaking. Thanks!

I have installed the new router, and set the same IP address as the old router, and now I can't find the Synology NAS. I can successfully PING it, and I also shut down the firewall to see if that helped, but no joy.  Any suggestions?
