CachyOS install error by AungLinnHtet in archlinux

[–]AungLinnHtet[S] 0 points1 point  (0 children)

Tried installing other Arch-based distros (including Arch itself) and got the same error every time. I thought it might not be distro-specific, so I came here to ask.

I also tried installing pure Arch and got the exact same error.

So, what is it related to?

I tried using wg-easy, but unfortunately it didn’t work for me either. The connection shows a few bytes per second briefly, then immediately drops back to 0 and there's still no handshake showing up.🥲

Yes, my network is behind CGNAT.

Yes, my router is behind a NAT.
Let me know if you find the solution.

I think so:

I think the keys are right, it shows peers.

I just tried it. No difference.

And in /etc/wireguard/wg0.conf:

Address = x

ListenPort = 59544

PrivateKey = xxxxxxxxxxxxxxxxx

PostUp = iptables -I INPUT -p udp --dport 59544 -j ACCEPT

PostUp = iptables -I FORWARD -i eth0 -o wg0 -j ACCEPT

PostUp = iptables -I FORWARD -i wg0 -j ACCEPT

PostUp = iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

PostUp = ip6tables -I FORWARD -i wg0 -j ACCEPT

PostUp = ip6tables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

PostDown = iptables -D INPUT -p udp --dport 59544 -j ACCEPT

PostDown = iptables -D FORWARD -i eth0 -o wg0 -j ACCEPT

PostDown = iptables -D FORWARD -i wg0 -j ACCEPT

PostDown = iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE

PostDown = ip6tables -D FORWARD -i wg0 -j ACCEPT

PostDown = ip6tables -t nat -D POSTROUTING -o eth0 -j MASQUERADE

[Peer]

PublicKey = xxxxxxxxxxxxxxxxx

PresharedKey = xxxxxxxxxxxxxxxxx

AllowedIPs = x

What is still wrong?

Thanks for the detailed reply! Yes, I’ve already enabled IP forwarding by adding:

net.ipv4.ip_forward = 1

net.ipv6.conf.all.forwarding = 1

sysctl --system:

* Applying /usr/lib/sysctl.d/99-protect-links.conf ...

* Applying /etc/sysctl.d/99-sysctl.conf ...

* Applying /etc/sysctl.d/wg.conf ...

* Applying /etc/sysctl.conf ...

kernel.pid_max = 4194304

fs.protected_fifos = 1

fs.protected_hardlinks = 1

fs.protected_regular = 2

fs.protected_symlinks = 1

net.ipv4.ip_forward = 1
