Doesn't work

[SergioXII12]

I tried both clean installation on CentOS8 and Debian 10 (server side), and Windows 10 and iOS 14.2 on client side.
No success. The windows wireguard client establish connection but without any internet access. Same for iOS client.
The installation script executed without any troubles.

did you a reboot after install wireguard?

[SergioXII12]

Definitely yes !

On your server, is there any config about firewall and iptables?

[SergioXII12]

No, just clean fresh installations on both distros.
No firewall (fully disabled). Script looks very logical simple and easy to use. So I'm frustrated where the troubles could be.
I completely understand how wireguard works and how to install it manually and I have working installation on one of my servers. But I like this script in terms of new clients adding and I cannot make it working.

Working for Debian 10: https://github.com/ah1102/wireguard-install/blob/master/wireguard-install.sh

need add: apt-get install wireguard-dkms wireguard-tools linux-headers-$(uname -r)

Could Not Resolve Host

Hello all,
It sounds like you need to edit /etc/sysctl.conf and uncomment #net.ipv4.ip_forward=1

sudo nano /etc/sysctl.conf
Remove # from #net.ipv4.ip_forward=1
Optional: ipv6: #net.ipv6.conf.all.forwarding=1
Then restart your system.

Let me know if this helped.

[SergioXII12]

I did it. Same result

Check your network resolve.
Try to ping to your client and server IP.
Then let see if it works.

[SergioXII12]

Of course all is pingable from both locations.

How about your firewall?
