Wireguard on Bullseye

Show all headers | View raw

I would like to set up a Wireguard VPN. I have followed the
instructions at
https://wiki.debian.org/SimplePrivateTunnelVPNWithWireGuard down to the
ping just above the heading "Routing configuration". The ping command
as given doesn't work:

root@iorich:/etc/wireguard# ping 10.0.2.1/24
ping: 10.0.2.1/24: Name or service not known
root@iorich:/etc/wireguard# 

However, striping out the /24 at the end helps.

I have both firewalls cleared, i.e.:

root@hawk:/etc/wireguard# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination         
root@hawk:/etc/wireguard# 


On the server, ping fails:

root@hawk:/etc/wireguard# ping 10.0.2.2
PING 10.0.2.2 (10.0.2.2) 56(84) bytes of data.

And on the client,

root@iorich:/etc/wireguard# ping 10.0.2.1

I did check the keys; they appear to be correct.

root@hawk:/etc/wireguard# wg show wg0
interface: wg0
  public key: HBkAW05W2zxbTGEE4FstJLxnBpfDpec3KGhSfs6BLCU=
  private key: (hidden)
