WAN Requirements for SpeedFusion Configuration

Knowledgebase FAQs
1

When configuring a SpeedFusion VPN connection, there are two aspects to consider:

  • Whether WAN connection has a Dynamic IP or Static IP.
  • Whether Peplink Balance unit has Public IP or is behind NAT.

Therefore, there are four possibilities for the type of WAN you use to establish the VPN connection.

  • WAN has Dynamic IP with Peplink Balance has Public IP.
  • WAN has Static IP with Peplink Balance has Public IP.
  • WAN has Dynamic IP with Peplink Balance is behind NAT.
  • WAN has Static IP with Peplink Balance is behind NAT.

The table below illustrates the system requirement for configuring Peplink SpeedFusion VPN connection.

Hi Erik, does that mean that we can establish a SF VPN to a central location without a fixed public IP address using dyndns per example?

I know this is quite an old topic, but did not want to create a new one if someone has a solution.

Cheers,

Hi Heriberto,

Yes, that is correct.
To be able to establish a PepVPN/ Speedfusion connection you need at least 1 static ip address OR a dynamic DNS address for 1 of the Peplink routers.
You can use DynDNS or Peplink’s own dynamic dns solution “find-my-peplink”.
Obviously we prefer our own dynamic DNS solution!
