    OpenVPN dnleak Merlin fw 386.3.2 rt ax56u

    I've just finished installing and manually configuring this new router and installing Merlin from factory default settings. I set up a vpn client with an ovpn configuration file, and policy rules to redirect vpn traffic. The Accept dns configuration is set to "exclusive" which I understand...

    VPN problem rt ac56u John's Fork

    Even though residual "debris" was apparently not an issue in this case I decided to clear all the settings anyway and re enter them manually just to see the effect. The end result was NVram utilisation went from 85% to 67%.

    VPN problem rt ac56u John's Fork

    Initially tried unsuccessfully to load 51D7 from 51D4 -three attempts with 3 reboots. At the end of the upgrade process the gui still showed 51D4. Then tried a reflash to E3 which "took". After that, reflashed from E3 to 51D7 which then worked. Low NVram warning then appeared. Used the...

    VPN problem rt ac56u John's Fork

    Thanks. I do understand that and it's quite possible that this residual "debris" is causing the problem. On the other hand it could be a problem with the firmware code. Anyway I plan to do a clean manual reinstall of the settings and this may resolve the problem.

    VPN problem rt ac56u John's Fork

    I plan to do that anyway because I'd like to refresh the settings etc in whole router. But that's not central to this firmware problem. ie the default vpn setting should clear settings but it doesn't. Clearly the router is confused because the gui indicates that there are active vpn...

    VPN problem rt ac56u John's Fork

    Pressing the default option in VPN did not clear the loaded vpn settings on my 56u. The settings remain on the gui and the certs are still in NVRAM (displayed after nvram show). Perversely, even though the gui shows the settings, after changing the service state to "On" the router goes...

    Asus rt ac87u: query about which is best firmware-merlin or asus

    I notice that this problem arose with the rt ac88u last year. One solution involved the creation of a special beta version his fw by Merlin. Since he no longer supports the rtac87u that’s not going to happen. I tried a downgrade to the very first version of the Asus fw using the normal gui...

    Asus rt ac87u: query about which is best firmware-merlin or asus

    I'm sorry I started this now. The firmware restoration tool won't allow me to restore to the most recent Merlin f/w. The "invalid f/w" message a short while after starting the restoration. Its all working but can't shift away from the latest Asus f/w. I have tried an earlier version of the...

    Asus rt ac87u: query about which is best firmware-merlin or asus

    I've always used the Merlin F/W (then Johns Fork) on my rt ac56u so I was not familiar with the stock Asus f/w. However for the 87u I thought the stock Asus f/w was the safest way to go. But after reflashing and exploring the gui I just didn't like it. Decided to try the Arch Phoenix...

    Asus rt ac87u: query about which is best firmware-merlin or asus

    I have an rt AC87u which I bought on Ebay some time ago with the idea of keeping it as a spare, or perhaps as a future replacement. It has the latest (and last) Merlin firmware which dates back to early/mid 2020. Still unused but I'm planning to activate it soon. Merlin no longer provides...

    Johns Fork rt ac56u possible problem

    re: Very Strange I repeated the process just to be sure I had waited long enough for completion ...and, yes the problem is as described. I found that a router reboot (but not a pc one) was needed to achieve a working system. Sorry to be the purveyor of bad news over the past few days.

    Johns Fork rt ac56u possible problem

    A possible new problem when using v51D4. Advanced/IPV6/ When changing from "native" to "disabled" there appears to be the same problem as reported at the beginning of this thread. The router hangs on "completed". and both a pc and router reboot is needed to achieve a working system...

    Johns Fork rt ac56u possible problem

    Now have tried the static route creation in this new version and it works perfectly. Thanks again.

    Johns Fork rt ac56u possible problem

    Thank you, I will try this. I followed up on your suggestion that dns filtering is the better way to go for what I wanted to achieve and it works beautifully. A very elegant way to force specific devices or groups to use a particular dns. And, easy to activate and deactivate. Finally I want...

    Johns Fork rt ac56u possible problem

    Yes I do have IPv6 active. Re dns filtering. I’m sure you are right..I’m just taking a few baby steps at a time in learning about all of this. Just fyi most companies offering anti geoblocking via dns show the static route option as the recommended way, and I haven’t seen any dns filtering...

    Johns Fork rt ac56u possible problem

    I created the static route to redirect from googles main dns 8.8.8.8 to the router gateway which uses a different dns. Googles chromecast apparently forces the use of 8.8.8.8 and I wanted to stop this. so 8.8.8.8. 255.255.255.255 192.168.1.10. 3

    Johns Fork rt ac56u possible problem

    Just updated to John Fork 374.43_51E3j9527 on an Asus rt AC56u. Created a static route for one device. After "applying" the new the router eventually shows "completed" and continues to show this even after quite a few minutes. It appears to me that the process never neatly completes but...

    Asus rt-ac56u: Last Merlin firmware 2 years ago, time to replace?

    Have now reflashed with John’s fork. The recommendation in the flashing instructions is to reset to factory settings. I’m holding off doing so because I want to keep my existing settings if at all possible. So far everything seems to be working well. To reconfigure manually would be a real...

    Asus rt-ac56u: Last Merlin firmware 2 years ago, time to replace?

    Thank you both. I will follow through with your suggestion. I’m just wondering what specific security vulnerabilities may now exist and how serious they may be.

    Asus rt-ac56u: Last Merlin firmware 2 years ago, time to replace?

    I have one of the wireless routers which does everything I need and is working perfectly. My concern is that the latest and last merlin firmware is around 2 years old. I am wondering whether there may have been security threats over the period since the last update, and if so should I...
