To: wireguard
I want to get iperf3 to benchmark a simple wireguard setup on my LAN.
I have two machines, foo is 192.168.1.228 and bar is 192.168.1.112.
These IP addresses are fully functional on their respective eth0
interfaces. Each one also has a wg0 interface configured as shown
below. I can get iperf3 to work over the non-wireguard interfaces,
but not over the wireguard interfaces. What am using iperf3 wrong?
Did I misconfigure wg?
Details:
Here are the /etc/wireguard/wg0.conf files for both machines (I don't
care if the public/private keys are present/this is only a test
environment and it will allow others to simply copy/paste if they want
to test as well):
On foo:
####
[Interface]
Address = 10.0.9.15/24
SaveConfig = true
ListenPort = 500
PrivateKey = kLac+M+JJJ+gpsKo1DeUyfuwfDwGeKMj81+M3Z3mUkw=
[Peer]
PublicKey = y6DrsFVIgqBMc8joSuEytCpQEywk5dPKRoeLZZC9H34=
AllowedIPs = 10.0.9.16/32
####
On bar:
####
[Interface]
Address = 10.0.9.16/24
SaveConfig = true
ListenPort = 500
FwMark = 0xca6c
PrivateKey = 4EwMqSyvLaHrv5JvAAyKnmdbw9UN4rsjydkPXb5ll28=
[Peer]
PublicKey = SkBs9t96znOr+d60tgPlXkp7z6YABvfxD9KNVzZIP3I=
AllowedIPs = 0.0.0.0/0
Endpoint = 192.168.1.228:500
####
Again, both wireguard interfaces are up and connected. For example, on foo:
# wg
interface: wg0
public key: SkBs9t96znOr+d60tgPlXkp7z6YABvfxD9KNVzZIP3I=
private key: (hidden)
listening port: 500
peer: y6DrsFVIgqBMc8joSuEytCpQEywk5dPKRoeLZZC9H34=
endpoint: 192.168.1.112:500
allowed ips: 10.0.9.16/32
latest handshake: 10 minutes, 41 seconds ago
transfer: 32.45 KiB received, 8.24 KiB sent
If I run iperf3 in server mode on foo and in client mode on bar, it
works as expected using the non-wireguard interfaces:
On foo:

When I try using the IP addresses of the respective wireguard
interfaces, I get nothing:

iperf -c 10.0.9.15
Also for the server, omit ipaddr, it listens to all interfaces by default.

I tried that but nothing:
On foo:
% iperf3 -s
-----------------------------------------------------------
Server listening on 5201
-----------------------------------------------------------
On bar:
% iperf3 -c 10.0.9.15
iperf3: error - unable to connect to server: Connection timed out

My mistake... I opened 500/udp for both sides... a quick fix was to
allow all from 10.0.9.0/24 and it works. Thank you for the reply.
On foo:
% iperf3 -s
:(
