Hello everyone,

I am not an expert, but I have been dealing with this topic for a while and would be incredibly grateful for your help and if there is a solution, a "step-by-step" guide would be AWESOME !!!

Is it possible to bring my DDWRT router into the network of my Fritz!Box, or to make the devices from the network of the DD-WRT router (AppleTV etc.) visible in the network of the Fritzbox? I only use the DD WRT router as a VPN router, which provides a special connection abroad for my AppleTVs at home.

I am super excited and look forward to your feedback with gratitude!

Best regards
Julian

Please state router model and build number.

See the forum guidelines with helpful pointers about how to research your router, where and what firmware to download, where and how to post and many other helpful tips:
https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=324087

After you posted your router model and buildnumber I will transfer this thread to the appropriate forum.


To already point you to a possible solution read on Smile

You can setup the DDWRT router as a Wireless Access Point (WAP).
The DDWRT WAP is on the same subnet as your ISP router so you have one seamless subnet.
See: https://github.com/egc112/ddwrt/blob/main/Wireless%20Access%20Point.md

However in order to use your VPN client you have to change the gateway address on your Aple TV pointing to the WAP, this might have unwanted other side effects so no guarantee that it suits your needs.
The VPN guides both for OpenVPN and WireGuard can be found as stickies in the Advanced Networking forum.

Hi egc,

sorry for my late answer, i just came back from holiday, so i couldn't check the actual firmware before.

Here are my stats:

DD-WRT v3.0-r53469 std (09/08/23) and its installed on a Netgear R8000. Smile
I have two Apple TVs that are directly connected with the Netgear R8000 via LAN /RJ45.

You can also see my VPN configuration in the attachment Smile

Those settings are not really "optimal".

To what kind of server are you connecting to?
Commercial VPN provider, self hosted VPS, other router?

You disabled default routing, why?

Your router seems connected to the Frirtzbox with its WAN port so your router is on its own subnet.
so only clients directly connected to this router can use the VPN is that what you want?

Hi egc,

it is a Commercial VPN provider (Private Internet Access).
Default routing is disabled because i only want to route specific domains,
as for example: NETFLIX and other Streaming Services should run on its original country (IP) where i am (because i cant stream from other countries). I only want to route the .ch and some specifiy domains, and that config. seems to work for 2-3 years now, even if i know, it might technically not be optimal. Smile

Exactly, that is the problem. Is there a way do add my router to the fritzbox subnet somehow and that my Apple TVs dont loose their VPN connection?

It is fine if you are doing the Policy Based Routing manually but there is also the built-in PBR, how to use it is explained in the guide.

Your really should review your settings, e.g. compression is a security risk and should not be used and there are a lot of other settings which need attention.
The OpenVPN Client setup guide has a paragraph about setup for PIA.

You can setup an OpenVPN client on a Wireless Access Point (WAP) but it needs some tricks.
You need to point your clients gateway to the WAP (this can be done manually or via DNSMasq) or make a guest wifi on the WAP, you can even add some ethernet ports to this guest wifi so that the attached clients to the guest wifi and the ethernet ports will use the VPN automatically. But then it is not so different from the setup you now have.

WireGuard is the better (faster/easier to setup) option then OpenVPN, but PIA does not support WireGuard on the router (with some trickery it can be done though), reason why PIA is not on the recommended list
