Using multiple devices with same vpn config

For WireGuard, can we use the same vpn client config on multiple devices and use them concurrently? I tried and speeds slowed to crawl and I was getting errors browsing the web.

For OpenVPN, is it possible to use multiple devices concurrently with same config? For OpenVPN, it generates same client config when you try to export; therefore, I think it’s not an issue in OpenVPN like it is in WireGuard?

Nope; you’ll have collisions when the different wgclient transmits the same public key… never mind endpoint IPs.

root@GL-AXT1800:~# wg
interface: wgclient
  public key: [redaced]=
  private key: (hidden)
  listening port: 37692

peer: [redacted]=
  allowed ips:
  latest handshake: 3 seconds ago
  transfer: 1.90 GiB received, 249.24 MiB sent
  persistent keepalive: every 25 seconds

IDK about OVPN; it’s too damn slow when compare to WG, regardless of what GL device you use (eg: Slate AX: 170 Mbps OpenVPN, 550 Mbps WireGuard, as advertised).
