Case Study – Router Upgrade – from 8Mbps to 200Mbps

We were approached by a client in central London to help with their internet connection. Although they had upgraded to Virgin Media’s 200MB/s DOCSIS3 service from a standard ADSL connection, they were still getting poor broadband speeds.

Old Hardware

As soon as we visited the site, the problem became apparent. They were using a Netgear FVS318v3 – this is a very out of date unit, that has a maximum throughput of 11.5Mbps. See the technical specifications here for a blast from the past: fvs318v3. Click here for more details..

Windows 10 – Change PPTP ipv4 Settings

In my RTM copy of Windows 10 Pro, when I try to edit the IPv4 settings of a VPN connection, nothing happened when I clicked ‘Properties’.

Thankfully, there is a solution to the issue – you can edit the file rasphone.pbk in a text editor like notepad.exe and make the necessary changes in this file.

The exact setting I wanted to change was to disable the default gateway – also known as split tunneling. This way I can connect to the VPN, and only tunnel traffic for that specific remote site over the VPN – i.e. use my normal non-vpn connection for internet traffic.

This is called “IpPrioritizeRemote”. I set this to 0 instead of 1 and saved the PBK file. When I re-established the VPN connection in the usual way, the ‘default gateway’ setting worked as intended.
