On some systems like Hetzner VM cloud i have a Point-to-Point interface so i have a peer address on the same line as my public IPv4 (look at peer here : https://linux.die.net/man/8/ip )

An example of `ip a` with peer is : 
```
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 96:00:00:a2:88:c2 brd ff:ff:ff:ff:ff:ff
    altname enp0s3
    inet XX.XX.XX.XX peer XX.XX.XX.XX/32 brd XX.XX.XX.XX scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::9400:ff:fea2:88c2/64 scope link 
       valid_lft forever preferred_lft forever
```

With a peer, the output of the command line 74 is : `XX.XX.XX.XX peer XX.XX.XX.XX`

I just modify this line with awk to print only the first field which is always the IPv4.
I think it's correct and it's work like a charm when there is a peer or not now. But tell me if it's not good for you :)

Thanks for your work !

If the FORWARD chain policy defaults to DENY, it must explicitly allow traffic from the external to the wg interface.
To solve this, the patch just adds
 iptables -A FORWARD -i ${SERVER_PUB_NIC} -o ${SERVER_WG_NIC} -j ACCEPT;

From https://www.wireguard.com/install/. Using kmod instead of dkms. Seems to work without reboot now.

Close #118 #111 #147

Hetzner also has their own Datacenter in Helsinki, Finland. Mentioning this for completeness.

Updated client name input restrictions and hint

Fix reboot message

An oversight from https://github.com/angristan/wireguard-install/pull/109

Ubuntu: remove PPA, use native packages
