That is indicating that you already have a route for those networks.

From the look of what it's trying to add, the remote side is pushing you a default route (redirect-gateway def1), and if your first vpn client is already doing that, the second one can't since the routes already exist.

Hi jimp,
thank you for the fast answer. I checked the routes what I have, but I can not see these routes, which should get added. Can you give me any hint, what I can check next - i have no idea why this is not working (it ever works).Any help is appreciated :)

I also see this when the loggin is on 6:

Dec 26 16:32:12 openvpn[71624]: Cannot open TUN/TAP dev /dev/tun2: Device busy (errno=16)
Dec 26 16:32:12 openvpn[71624]: TUN/TAP device ovpnc2 exists previously, keep at program end

Hello,

I solved it by myself and this issue disappears. I changed from TUN to TAP device in configuration, renew the DHCP Lease for the virtual adapter and it works like a charm.

I had the exact same issue a bit earlier and it was driving me nuts as it seem only to happen when I was adding a 2nd VPN connection. The first exactly configured the same was working fine.

I rebootet pfSense and all worked like a charm
