Vendor firewall is blocking communication

Setup a new Netgear Nighhawk AC 1750 day before yesterday.  I've got everything working... all devices connected, etc.  There are no issues connecting to the Internet when not using VPN Software. Also, I bypassed the router straight to the Charter Spectrum modem and VPN software worked fine.  Have tried with Freedome and Tunnel Bear VPNs.  After about five minutes of internet use, the connection drops.   Windows 7 trouble shooter states: "Vendor firewall is blocking communication.  This UDP communication with IP 198.x.x.x and svchost.exe blocked."  (IP address is a VPN IP). ... I'm not going to download something like DDWRT, etc as this is a family members computer. 

 UPDATE: Last night, I was on the phone with a NG Sr Level Tech.  At first, he took me to: Advanced>Advanced Setup>Port Forwarding>Add Custom Service.  However, after further discussion we ended up updating the bios via Netgear Download option and resetting the modem from the menu.  When we came back, he then took me to Advanced>Setup>LAN Setup> added a specific computer for a reservation.  Then, he took me to Advanced>Setup>WAN Setup> Checked "Default DMZ Server"  with that same computer.  Both VPN programs then appeared to work fine.  Since I had no experience with DMZ, I asked him what it was ... he said something like "it is our VPN".  It was very late and we ended the call.  After getting off the call, I searched the Netgear site and found a "Netgear" article that stated: "Warning: DMZ servers pose a security risk. A computer designated as the default DMZ server loses much of the protection of the firewall and is exposed to exploits from the Internet. If compromised, the DMZ server computer can be used to attack other computers on your network."  So, I reversed the settings back to default.  Back to square one.

Windows 7, Norton Security Premium

Any suggestions?  Let me know if you more details.

TIA!

Re: Vendor firewall is blocking communication

It seems odd that you have a connection for 5 minutes before it fails. If it were a firewall issue, whether Windows or Norton, I would think that you would not get a connection in the first place. 

Try disabling the Norton firewall temporarily to test the VPN connections. Right click on the Norton icon in your system tray and click on Disable Smart Firewall. Then test.  This should diagnose whether Norton's firewall is involved.

Thanks for the quick response.  After about 7 minutes, with the Norton Smart Firewall disabled, I was kicked off.  Browsed around the Norton site. 

I thought it was strange too that it was kicking me off after five minutes or so.  Late last night, I reinstalled the Freedome software after updating and restoring the router.  I did notice on another VPN's web site that they did not recommend Netgear routers.  On another, they showed how to download their custom firmware to a Netgear router.

If you were still disconnected with the Norton Firewall disabled, then I would suggest Norton is not involved and you need to look elsewhere for your problem.
