VPNMON VPNMON-R3 v1.9.1 -Mar 14, 2026- Monitor OVPN/Wireguard + Multi/Double-Hop VPN + WAN Health + Random Reset (Available in AMTM!)

[Tarek Yag]

Super incredible. Congrats @Viktor Jaep for this great new release full of improvements and new additions!!
Updating my instance now...

Super excited to tease a brand new VPNMON-R3 feature... coming to a BETA your way soon! Double-Hop VPN!

Capable of selecting and configuring an inner and outer VPN tunnel, and when using 2 different VPN providers, gives you some of the best possible privacy available. Unique to VPNMON-R3 and this Asus Merlin Community, this feature also lets you use straight OVPN and pair it with a WG tunnel, or WG with OVPN, WG with WG or OVPN with OVPN.

Still doing lots of testing and cleanup... but hoping to get this out in your hands within a few more days!

 

[Viktor Jaep]

Shhhh... For anyone interested in wanting to test the first pre-release beta1... I've made it available. This is practically Alpha... All menus look clean, functionality looks good, will be making a few more tweaks here & there. Use at your own risk, and let me know how it goes!

VPNMON-R3 v1.9.0 Beta 1- (February 25, 2026)
- MINOR: Added an extremely unique feature to VPNMON-R3. Multi/Double-Hop VPN! While this kind of functionality is available using major VPN providers, this is not a feature I have come across in the Merlin FW world as of yet. This feature is capable of selecting and configuring an inner and outer VPN tunnel, and when using 2 different VPN providers, gives you some of the best possible privacy available. Unique to VPNMON-R3 and this Asus Merlin Community, this feature also lets you use straight OVPN and pair it with a WG tunnel, or WG with OVPN, WG with WG or OVPN with OVPN. This option is available under the configuration menu -> Option #17. A full menu to manage this feature has been added that lets you pick which VPN/WG slots, Hop Clients, and Advanced Settings if need be, along with the ability to enable/disable, rebuild, and tear down routing rules.

Getting VPNMON-R3 v1.9.0 out the door after a few weeks of testing Multi/Double-Hop VPN on my end. Everything seems to be functioning as advertised. Would love to hear your feedback. Hope you all enjoy!

What's new!?

PLEASE NOTE: Double-Hop VPN Client redirection is handled within the VPNMON-R3 interface, not through the VPN Director in the main Merlin UI.
- PATCH: Various inconsistencies and bug fixes around bandwidth measurements.

Small bug fix day on one of my favorite days of the year... 3.14 - happy Pi-Day!

What's new!?
v1.9.1 - (March 14, 2026)
- PATCH: Because it's Pi-Day, we're celebrating with a small patch release along with a nice slice of Pizza pie! This bug fix resolves an issue that I thought I caught last go-around, but it was still showing bad behavior. Primarily related around the connection throughput indicator visuals, when the figure exceeded the lower and medium display bounds (configurable using option #14) only for the OVPN, it would use the TX values instead of the RX values. This all stems around the fact that for some reason, RX and TX values are reversed for OVPN, but not for WG, when gathering these stats from the underlying system.

Call it what you will, OCD or whatever, but just making sure when everything is supposed to be green, everything is green. Fixed!

and it's killing working vpn connections even manually started

Sounds like it's having problems determining if your WAN is up on your router. Until we've sorted this out, you could just disabling that functionality in the setup (vpnmon-r3 -setup -> 1 -> 8 add'l WAN monitoring)

You doing anything unusual when it comes to your WAN? What are you using for your Ping host? Could you be blocking anything?

no, behavior just changed with 1.8.3, I think it may be related to dual wan

 

[Viktor Jaep]

So you are running dual WAN? What are you using for your pinghost? Do you know what network interfaces are assigned to WAN0/WAN1?

I'll compare versions and see what might be different that could be affecting you.

I'll also send you a link to see if you can try 1.8.3 (or a version prior) to see if they work for you, which could help troubleshoot this.

I have compared the main functions dealing with WAN outages between 1.9.1 and 1.8.3, and have not found any differences. Perhaps it is something else!?

Please give v1.8.3 another try, and see if this doesn't cause the same behavior that you're seeing - run the command below to overwrite your current version of VPNMON-R3 with v1.8.3:
