Question

Very weird problem with my NAS

Let me briefly describe my network:

I have a TP-link Archer D5 router acting as a wireless router connected to gigaset sx763 router acting as a modem.

To the router by ethernet I have connected a Seagate Central NAS (3TB version) and a d-link powerline 308AV adapter.

If I connect my PC to the router using wifi I can access everything on the NAS and configure and do whatever I want.

If however I connect via ethernet or powerline (310 AV) I can access the internet and any usb attached to the router but I can't access the NAS.

The error I get is: The specified network name is not available.

Central uses a static IP outside of the dhcp range and responds to a ping using wifi and ethernet.

I have tried 4PC's using xp,vista and windows 7 (32 and 64 bit) but it can't be seen via android (on powerline) or wdtv.

I would really appreciate any help/advice as I really tried hard and would hate to leave it not working.

Any ideas would be appreciated.
Thank you very much.

Can be true.

Many routers have firewalls even for the LAN. Since a router's NAT system is a natural firewall to the internet you have to ponder why folk turn on a firewall to their LAN. Your choice. Here I turned off my Archer's firewall.

Thank you for your reply

Would you elaborate a bit on what is your idea?

I believe I tried the setup with firewall disabled, I will do so now again. I don't really know much about this but I was under impression that the firewall only blocks "external" stuff, I have seen a recommendation to turn it off and tried that way to no avail.

About NAT, you mean Network attached time? I turned that off as it was causing the seagate to boot up 5 minutes after it finally went to stand by, some stupid glitch they had.

Also the folders on the seagate say they are windows server 4.9, while I was under impression central is linux based, (also related to that NAT problem I had (and still have to a lesser extent))

Finally I have recently noticed that while I can't access the drive from explorer a P2P connection seemed to get through, uTorrent was able to download a file to central while my laptop was connected via powerline (so via ethernet).

I am really confused with this and I would be eternally greatful to anyone who might help.

Sorry no.

It's a setting you must choose. As to NAT, that's a function in all consumer routers today. I would have to write a book to detail how it works so let's keep it simple. A setting you can try.
