Enabling VPN service stops internet : XR1000 1.0.1.82_1.0.67

[BSilverthorn]

Just updated to XR1000 1.0.1.82_1.0.67 on my XR1000. When I enable the VPN service using UDP or TCP my router stops routing packets out to the internet. So anything on the internal lan fails to route out to the internet.

Once I disable the VPN service on the router  everything immediately starts working again.

Items I have tried: (more than twice each)

• reflashed firmware
• Factory default through web browser
• Factory default using reset button
• Created VPN on differnt ports using UDP
• All three options for connection access as well

 

Router seems fine until I enable the VPN service.

This is a NTGR feature so our experience with it will be limited but I can't imagine how that is happening considering there isn't a VPN connection alive until you actually connect a client to it and there are essentially no options for it. Once you've enabled if you just do a reboot is the connection restored and are you able to connect to the VPN?

[BSilverthorn]

A reboot does nothing.  I have not tried to connect yet.  Haven’t been anywhere remote.  It’s very odd. Once disabled all works.  It’s like a kill switch.  I can enable and it quits, disable and works on the fly.

Cela semble normal !

Si tu n'as pas suivi les instructions pour configurer le client en avale... il perd la connexion !

You don't have to be remote but could you try initiating a connection to it just in case it requires that please? I don't see why it would.

What is the model of the modem/router the XR is connected to and how have you set that to ensure all traffic flows to the XR? E.g XR in its DMZ, modem/bridge mode. It does require a direct line to the internet so if you haven't done that then that could be a reason it's not behaving correctly.

[BSilverthorn]

It’s in the DMZ on the backend of a Verizon modem.  I’ll try and connect later and see. It’s worked in the past just fine and my other routers work fine mimicking the same setup. Obviously on different ports.  Ports are forwarded etc.  I can’t get to the testing phase yet as it stops routing per se for all Lan connected devices.  I will try when I get back home.  It’s offline atm.  
 

so to be clear it’s not the client side.  It happens when I check the box enable VPN service on the router. Once clicked the lan devices can no longer reach the internet behind the XR.  Turn it off and it all works.

You said it worked in the past, what happened in regards to settings/hardware changes between then and now?

Did a firmware upgrade to the one listed in topic section. Factory reset a few times and thats it. Everything else is the same. Small network, it stays pretty static unless somone brings an xbox over the like. Been the same for a few years. I might try and go back a build and see what happens when I have more time to spend with it. Spent a few hours today trying to figure out when I should have been working ;-).

Yeah do try a previous version and let us know. We certainly don't change anything in the settings and anything we do wouldn't affect it. I know it works as expected on the 500, never personally tested on the 1000 but should work the exact same.
