Site VPN

The PFW plugin from PLUS adds support for Site VPN Destinations with Wireguard.

Configuration​

Once PFW is enabled, a new menu should appear under the VPN view.

plus-site-vpn-view

Next, fill out the wireguard details. The 'Interface Address' should be the Peer IP for SPR that the remote wireguard has assigned. plus-site-vpn-config

Routing Traffic​

Next, we can use the PFW extension to create Policy rules that redirect traffic over the site interface.

Select the Forward all traffic to ...Site VPN or Uplink action plus-site-forward-site-flow1

Fill out the parameters, selecting the Client/Group/Tag to apply the rule to. Select the site0 destination itnerface. The destination can be left blank for Site VPNs.

plus-site-forward-site-flow3

Now outbound traffic from the selected device will go out over the Site VPN.

DNS Split Tunnel​

Note that DNS request still go through the main router DNS service. In a future release, a parameter will be available to also route DNS queries through the Site VPN.

Verifying connectivity​

In an upcoming release, status will be visibile in the UI. For now, users can run the following command on SPR

docker exec -it superwireguard wg show
interface: wg0
  public key: PUBKEYPUBKEY=
  private key: (hidden)
  listening port: 51280

interface: site0
  public key: PUBKEYPUBKEY=
  private key: (hidden)
  listening port: 52538

peer: PEERPUBKEYPUBKEY=
  preshared key: (hidden)
  endpoint: 1.2.3.4:51280
  allowed ips: 0.0.0.0/0
  latest handshake: 11 seconds ago
  transfer: 272.20 MiB received, 50.05 MiB sent

And check that the site0 interface has the correct peer IP

docker exec -it superwireguard ip -br addr show site0
site0            UNKNOWN        192.168.241.2/32
