Split Tunnel Between VPN and ISP Connection or Two VPN Connections

In an ordinary VPN split tunneling scenario, you can split-tunnel your network traffic between a VPN connection and direct Internet connection. That scenario is completely supported on the pcWRT router. Moreover, since the pcWRT router supports up to three concurrent VPN connections, you can also split tunnel between two VPN connections.

There’s no extra configuration needed to split tunnel between two VPN connections, except that you need to set up two VPNs on the router. Then you can simply select another VPN as the alternative route for split tunneling.

Split Tunnel by Domain Name, IP address and Country Code

You can list domain names (or partial domain names), IP address ranges and country code in the split tunneling exception list. If you enter “uk” or “.uk”, then all domains with the “.uk” suffix will match this rule. And you can enter IP address ranges in CIDR format, such as 23.23.189.144/28 and 34.195.253.0/25.

If you want all UK traffic to go through a VPN connection to the UK, then you can enter a country code like this: geoip:GB, where GB is the two-letter country code for the UK. A full list of two letter country codes is available here: https://www.iban.com/country-codes.

Block Outbound Traffic with a Faux VPN Connection

If a VLAN is configured to use a VPN but the VPN connection is not available, the pcWRT router will block access to the Internet. As such, you can configure a faux VPN connection with split tunneling to block outbound traffic for the listed domains and IP addresses. Select “Tunnel only the domains and IP addresses listed below” and enter the IPs and domains you want to block, as shown below.

Here, no VPN is set up. But only domains and IP addresses listed in the Split Tunneling box are configured to send through the VPN. The listed domains and IP addresses are thus blocked because no VPN is available.
