Enable a VPN connection

Enter the interfaces that you want to use for establishing a VPN connection.

The Runtime container can establish a VPN connection with the interfaces specified in the VPN_ADAPTERS variable. Enter the interface names separated by commas. For instance: eth0,eth1,eth2.

Note: If you establish a standard network bridge interface, the setuphost container creates both a tap and a bridge, if not yet in place, for each specified interface in the VPN_ADAPTERS. For every tap and bridge created, the network bridge interface aims to append the suffixes -tap and -bridge at the end of the name, respectively and considering that in a Linux environment the maximum length for a network interface name consists of 15 characters.
  • Example without truncation:
    • Adapter name (characters length 4) = eth0
    • Tap name (characters length 8) = eth0-tap
    • Bridge name (characters length 8) = eth0-bridge
  • Example with truncation:
    • Adapter name (characters length 9) = enp0s31f6
    • Tap name (characters length 13) = enp0s31f6-tap
    • Bridge name (characters length 15), note the truncation of the original name = enp0s31f-bridge.
The limitation on maximum length could potentially result in conflicts for both bridge and tap interfaces with a name of similar lenght or longer.
