Cisco Anyconnect VPN - WNDR3700 works - Nighthawk XR500 doesn't work
Hello,
I've tried searching through the discussions/faq's and can't seem to find a solution to my VPN issue.
I have a work laptop with Cisco Anyconnect VPN software installed and it can c...
Hello, could you try disabling QoS from Anti-Bufferbloats' 3 line menu please and see if that resolves the issue?
I'm having the same issue with Cisco AnyConnect VPN not working with the XR500, and Firmware v2.3.2.56?
I've connected Netgear, and they are looking into it, but it's strange that I can find quite a few threads regarding NetDuma OS not working nicely with Cisco AnyConnect...
One observation in my case, Cisco AnyConnect (Macintosh) works fine. Cisco AnyConnect (Windows 10-64bit) does not work.
The Windows version reports:
- Connection Attempt has failed (error in response data)
- The AnyConnect Client service is not responding. A VPN Connection Cannot be established.
If I bypass the router, and go directly to the cable mode, AnyConnect Windows works fine.
From this thread, we know this has been investigated at least as early as 2019-03-14? Any chance that NetDuma has some better information or a more updated Firmware that Netgear hasn't released yet?
No sadly not. I imagine this issue has something to do with UPnP not facilitating the connection correctly. Maybe some manual port forwarding is required?

Well, turning off QOS immediately resolves the issue, and allows Cisco AnyConnect to work fine. The UPNP settings appear to have no affect, regarding this issue.
By Turning off QOS, I mean turning off QOS, Hamburger Menu, Turn off QOS.
I have tried setting up Triggers, etc for Port 443, which is the only port that Cisco AnyConnect needs, and had no resolution (other than turning off QOS).
And to stress again, this applies only to the Windows version of Cisco AnyConnect. The Macintosh version worked fine, even with QOS enabled.
So as mentioned above in this thread, QOS Appears to be the culprit, for a Pro Level router, QOS shouldn't be breaking a work related function such as VPN.
When is this going to be investigated, and resolved? This was reported 6 months ago, and disabling QOS to be able to use a VPN, doesn't seem like a acceptable long term solution.
Why should VPN users not be able to use QOS?
This is especially a concern for me, since I purchased this specifically for the NetDuma OS. I was impressed by the LTT coverage of it, and specifically stepped up to this model because of it.
That being said, it's now a liablity since I can't throw an alternative firmware up onto the unit.Sorry, this turned a bit ranty, but I'm having flashbacks here to the Portal Router, which I backed, and wasn't supported with decent firmware upgrades. When it worked, it was great, but I bought NetGear because I expected that issues like this wouldn't happen, and if they did, they would be resolved in a timely manner.
Not being able to use QOS & a external VPN, seems like a problem that should be fixed in a timely manner.
I agree that this is a problem but in my experience most of our customers use Hybrid-VPN instead of a VPN on their devices. The advantages to this are obvious, especially when it comes to gaming performance. Not to mention, Hybrid-VPN works with consoles.
As a gaming focused product, our primary concern is with Hybrid-VPN rather than the compability of desktop based business VPNs. That said, as you know, we are aware of this problem and we will be working to fix it.
