Abstract

A respective VPN routing table for each of a plurality of VPNs can be stored on a client device. The client device can access a first VPN routing table and, using the first VPN routing table, establish a first VPN tunnel to a first VPN. The first VPN can be a first subnetwork assigned a particular network prefix. While the first VPN tunnel is currently active, the client device can access a second VPN routing table and, using the second VPN routing table, establish a second VPN tunnel to the second VPN. The second VPN can be a second subnetwork assigned the same particular network prefix as the first subnetwork. While the first VPN tunnel and the second VPN tunnel are simultaneously active, the client device can communicate data to remote devices in the first VPN and the second VPN using the particular network prefix for both.
