Wireguard breaks internet access on Fedora 34

angryJellyBean · 10-26-2021, 10:25 PM

Hello I am having issues getting Wireguard running on Fedora 34. Whenever I start it with

Code:

wg-quick up wg0

Everything looks fine and

Code:

sudo wg show
interface: wg0
  public key: xxxxxxxxxxxxxxxxxxxxxxxxxxx
  private key: (hidden)
  listening port: 51820
  fwmark: 0xca6c

peer: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
  allowed ips: 0.0.0.0/0, ::/0

seems to show as it should.

But then internet access is broken. This occurs even if I set selinux to permissive and disable the firewall.

Here's my wg0.conf

Code:

[Interface]
PrivateKey = xxxxxxxxxxxxxxxxxxxxxxx
Address = 192.168.50.233/24
ListenPort = 51820
PostUp = iptables -A FORWARD -i %i -j ACCEPT; iptables -A FORWARD -o %i -j ACCEPT; iptables -t nat -A POSTROUTING -o eno1 -j MASQUERADE
PostDown = iptables -D FORWARD -i %i -j ACCEPT; iptables -D FORWARD -o %i -j ACCEPT; iptables -t nat -D POSTROUTING -o eno1 -j MASQUERADE

[Peer]
#op9pro
PublicKey = xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
AllowedIPs = 0.0.0.0/0, ::/0

Any ideas where I should be looking to solve this?

Maybe you can get help with fedora issues on the askfedora forum.
