Note that we only provide support for hardware supplied by Vorco. This applies even if you have purchased a router or firewall elsewhere that is an identical model to one that Vorco supplies. This is because the hardware we supply comes with specific firmware versions and configuration settings that meet the specifications of the service we are supplying and are connected to management systems on Vorco's side.

We understand that customers may wish to use their own router or firewall and provide the below information to assist.

RFC4638 - 1500-byte MTU over PPPoE

We support RFC4638 which allows you to use a standard 1500-byte MTU on PPPoE. Most up to date routers and firewalls support this and you should ensure you enable it to avoid issues with 1492-byte MTU in some instances.


Vorco fully supports IPv6, and you should enable it if your hardware supports it. All PPPoE connections come with a static /56 prefix delegation by default. To utilise this please enable DHCPv6 Prefix Delegation on your PPPoE connection.

Connection Monitoring

Vorco pings all connections every 60 seconds which allows us to track uptime, latency, and jitter. This relies on your router or firewall responding to ping requests.

If your router or firewall is restricting ICMP and ICMPv6 ping requests, please configure it to respond to ping requests from:

  • (

  • (

  • 2404:5700:D::/64

  • 2404:5700:FF02::/64


We advise using the Vorco DNS servers to ensure that Content Delivery Networks (CDN) serve you content from as close as possible. If you use other DNS servers, you may experience suboptimal performance. Our DNS server addresses can be found here.


We recommend using NTP servers that are geographically close, to improve time accuracy. Our NTP server addresses can be found here.

VoIP Compatibility

If you are using Vorco Voice over IP services, also see our article on

Voice Services - Network Setup Requirements to ensure your router or firewall does not block voice traffic.
