Asus made some major changes to how nvram is handled on this router, to help protect against buffer overruns (now each nvram value has a declared maximum size for instance). The new Broadcom SDK also handles nvram differently from past platforms (with some new restrictions), causing further issues. Finally, I suspect Asus just rewrote a lot of their OpenVPN implementation, since it's now closed source. All of this combined together has created a lot of separate issues with OpenVPN.
The good news at least is that all of this is fixable. I'm still sorting through all those similar issues with my own firmware code at the moment, and I'm starting to get close to having the whole OpenVPN implementation working properly again, one fix after another. This time however Asus will have to fix the stock FW implementation on their own, as I can't fix their closed source code... And this time, I've put a GPL licence on my own code. Lesson learned.
Hi Merlin,
Forgive me as I'm not as technical as you guys, does the above mean that you are working on a firmware version for the GT - AC 5300?
I just need to know if I'll ever get the option 61 if I purchase this router, my ISP won't authenticate without it, unless there's another way around the issue?
