PPTP VPN instable
The PPTP VPN of our FVS336Gv3 is configured according to instructions in KB article. I connect to FVS336Gv3 from home, using a Windows 10 VPN Client. The Win LAN address is 192.168.0.0/24, when connecting VPN adapter gets a 192.168.50.0/24 IP (DHCP 100..110). Since machines in the FVS336Gv3's LAN have 192.168.100.0/24 like IP, I can't access 192.168.100.0/24 machines directly, I have to add route entry:
route add 192.168.100.0 mask 255.255.255.0 192.168.50.100
After this ping gives echo, and I can work using Remote Desktop.
My problem is that the VPN connection is not stable, after some minute (random) the connection freeze. Windows 10 recognize nothing about it, it shows that VPN is still connected, although I no longer can ping 192.168.50.100 or any machine in the remote network. I have to reconnect VPN, add a route again. Many of my collegaues struggle with the same problem. We checked the internet connection, it seems stable.
Any ideas would be greatly appreciated. Thanks, Gyula
Hi BGy,
You're welcome! :) I'm glad you have configured L2TP/IPsec successfully and it seems this works best for you.
Since you have chose L2TP/IPsec over PPTP VPN, I encourage you to mark the appropriate reply as the “Accepted Solution” so others can be confident in benefiting from the solution. The NETGEAR Community looks forward to hearing from you and being a helpful resource in the future!

Hello BGy,
Welcome to the community!
What firmware version are you using? Did you try performing a continous ping test to any website and see if it has time outs?
Thanks,
Version is 4.3.4-2. I tried continous ping test: when RDP freeze, I no longer can ping 192.168.50.100 or any machine in the remote network.
I guess stability depends on the traffic. I left alone my machine after establishing VPN connection. After 2 hours, it was still connected but when I opened RDP it freezed after some second.

Hi BGy,
How many users are connecting via PPTP? Note that the FVS336Gv3 has a maximum of 25 simultaneous PPTP user sessions only.
What authentication are you using? You can probably lower it to PAP only.
You could also consider using L2TP as it has about double the throughput over PPTP VPN. It might help the connection.
PPTP has around 6.5 Mbps while L2TP has 11-13 Mbps.
