Unfortunately, at least for the RT-AX86U Pro router, Merlin is still on a 3.0.0.4 base, and as far as I can tell, ASUS only fixed the WAN failover issues in 3.0.0.6.
Totally agree. Also, the WAN Failover script is 6792 lines of code, which is just totally scary for me.
I am using 3.0.0.6 stock firmware on both AX and BE routers and the WAN failover basically works okay. It has been 100 % reliable to failover. It's a bit of a lottery about failing back...
Hello,
I have observed something similar with the RT-AX86U Pro. I'm running the Stock ASUS Firmware (3.0.0.6.102_34336 -- latest version as of 3 March 2025) and I'm getting a steady increase in dropped packets on br0 (my LAN bridge). About 3 dropped packets per second. This is what...
Hi Jeffrey,
I wouldn't hold your breath about ASUS fixing this. I have spent countless hours on the phone with their top tier support folks (and also collecting logs for them) and they show no sign of understanding the problem and no inclination to make any effort to do so. Super...
I have an EXTERNAL UBUNTU 24.02 VPN SERVER that is running Wireguard (along with Linux GRETAP) to create a Layer 2 bridge between two homes on both sides of the Atlantic ocean. The setup is almost identical in each house except on the USA side I have an RT-AC86U and on the Europe side I have an...
Hi Dave,
Thanks for your reply.
I figured out why "service restart_ddns" wasn't doing what I expected after my script detected a new Public IP. I can see in the syslog that restart_ddns was returning
Oct 8 10:06:42 rc_service: service 30986:notify_rc restart_ddns

Hello,
I have an ASUS RT AX86U Pro running the latest stock firmware -- 3.0.0.6.102_34314. I would like to avoid running Merlin if possible.
My router is behind another ISP fiber router so I have a double NAT issue (I tried PPPOE but I lose my IP address periodically and never get a new...
Hello @Kingp1n,
Can you tell me what exactly isn’t working with the ASUS version of Failover. I’m finding it working perfectly except for this one issue where after Failback I have the Seconday WAN in “Hot Standby” instead of “Cold Standby”. Is this something the script you linked to fixes...
PART 2
NOW I PLUG FIBER CABLE BACK INTO ASKEY ROUTER
After Failback, Primary WAN connected and Secondary WAN in “Hot Standby”. BAD!
Primary WAN (ppp0) is UP and has a public IP address again:
ppp0 Link encapoint-to-Point Protocol
inet addr:88.1.192.55 P-t-P:192.168.144.1...
Hello all,
I have an RT-AC68U with 386.12.4 firmware. I am successfully running a Dual WAN with the Secondary WAN set up for Failover + Failback. (I'm actually kind of surprised it works so reliably, given the many references I'v seen in this forum to a user-script to take the place of the...
Hello @Ranger802004 ,
Thank you for your very hard work. You have obviously put a huge amount of time into this project. I am wondering if you can tell me whether your WAN failover solution will solve my specific problem?
I have an ASUS RT-AC68U with the latest Merlin FW.
My primary WAN is a...
It's 4+ years later and something similar just happened to me -- only I was trying to reach a router over the Internet 6000 miles away.
I got the login screen but after that no page would load. Looking at the macOS safari console screen, I could see that the element that was hanging on the...
Oh, and just to be clear, if I set the IPV6 address in the DDNS record, I did not have to override the server address in the iPhone OpenVPN client. If I did NOT set the IPV6 address in the DDNS record, I had to enter the router's IPV6 address in the "Server Override" field in the VPN client.
Hello @Logi . I honestly don't know exactly how this is working. You might want to try to install the Asuswrt-Merlin firmware if the stock firmware doesn't have the needed IPV6 setting.
In my case, I simply enabled passthrough and rebooted my router and then I could see that the router got...
Hi @glens. I too assumed the IPV6 address would remain constant but I called Xfinity tech support to ask and they said "it will change from time to time". It's possible the guy had no idea what he was talking about. As I only just enabled IPV6 yesterday, I haven't seen any changes yet...
