QNAP NAS Community Forum

Hello
(I am not a complete tech expert, so I hope the following question makes sense...)
I am using a QNAP TS-451 in my office and would like to use a dedicated QNAP TS-251 at my home as an off-site backup. Problem is that my ISP does not allow port forwarding. At home I use internet through a 4G Huawei router (no landline) and even though I can enter port-forwarding settings (called "virtual server" with the Huawei E5770) the ISP has a permanent firewall that blocks this. Whenever I test (with online tools) if a port is open, I get a negative message (even though I have opened / forwarded it).

Is there any way to do off-site back-up (RTRR or versioning) that I can set up without relying on port forwarding?
thank you for any support

You're presently trying to 'push' the data from your office NAS to your home NAS.

You might try creating the backup job in a 'pull' configuration. The job is run only from your home NAS and 'pulls' the data from your office NAS. Suggest using a VPN between the two. You still need to forward ports, but only at the office end.

Also: 4G? Hope you have a good data-plan.

Dear OneCD
that's a great idea. Thanks.
But how do I do a 'pull' configuration? When I go to RTRR / "Create Replication Job", and chose 'Backup' then the option of remote folder to local folder is greyed out.
thank you for any help on this

Sorry, I don’t have access to the current QTS backup utilities so I’ve no idea what options are on-offer. Maybe someone else can advise?

... and did you establish port-forwarding at the office end?

Yes, this is all working.

So... how can my home NAS pull the data from my office NAS ?? I did not find anything on the forums that tells me how to do this.
any help is much appreciated!
