Hello!

I have a TP-Link Archer C7 v4 router. I would like to use it as an OpenVPN client, but XOR patch support is absolutely required, since my VPN server is configured with obfuscation (scramble), and without it the router simply fails to connect (tested — connection does not establish without scramble).

Could you please help me with the following:

1. Is there a DD-WRT build for my router that supports OpenVPN with XOR patch?

2. If yes, could you provide a link to the correct firmware image or build (ideally with version/date)?

3. Do I need to build a custom firmware with scramble support myself? Or is there a custom build available somewhere?

Thanks in advance for your help!

Just curious what firmware is your server which has the Scramble options?

Scramble options are standard built into DDWRT

OpenVPN guides are a sticky in the Advanced Networking forum to which I will also move this thread:
https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=327398

The DDWRT OpenVPN Client setup guide has a paragraph about it.

About builds, 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:

Latest build as of today 61557

N.B. The WireGuard software in DDWRT also has scramble options but both sides (client and server) must use DDWRT to work.

Thank you so much egc & kernel-panic69! I was able to flash the router successfully — everything is working now.
At first, the configuration import didn’t work correctly: only the certificates were imported, and the rest of the settings were missing.
I manually configured the client using the original config as a reference — and the connection started successfully!
