Can not edit config to run on port 53? (function get_free_udp_port)

[ishmumx]

I edited the portion of the code to give me 53 for a random lookup so my final config has port 53 in it:

function get_free_udp_port { local port=$(shuf -i 053-053 -n 1) ss -lau | grep $port > /dev/null if [[ $? == 1 ]] ; then echo "$port"

also tried

function get_free_udp_port { local port=$(shuf -i 053-053 -n 1) ss -lau | grep $port > /dev/null if [[ $? == 1 ]] ; then echo "53"

And none of this works. In the end, I end up with this:

Try `iptables -h' or 'iptables --help' for more information.
Created symlink /etc/systemd/system/multi-user.target.wants/wg-quick@wg0.service → /lib/systemd/system/wg-quick@.service.
Job for wg-quick@wg0.service failed because the control process exited with error code.
See "systemctl status wg-quick@wg0.service" and "journalctl -xe" for details.
Client config --> /root/client-wg0.conf
Now reboot the server and enjoy your fresh VPN installation! :^)

Can someone help so I can install wireguard to Port 53? Seems like if I replace it with a 3 digit number, it works (053 doesn't work I tried)

You can make it easier, run it with environment variable SERVER_PORT=53

SERVER_PORT=53 bash wireguard-install.sh

Unfortunately that did not work either.

Result is the same:

net.ipv4.ip_forward = 1
net.ipv4.conf.all.forwarding = 1
net.ipv6.conf.all.forwarding = 1
Created symlink /etc/systemd/system/multi-user.ta
rget.wants/wg-quick@wg0.service → /lib/systemd/sy

ontrol process exited with error code.
See "systemctl status wg-quick@wg0.service" and
"journalctl -xe" for details.

Now reboot the server and enjoy your fresh VPN in
stallation! :^)

@l-n-s any comment on this? You can try with any Debian Distro and it will show this.

My Debian machine works fine.

Have you tried to do a clean install? Either uninstall everything and remove all the config files (if you can). Or reinstall the OS.

Yes I have. Brand new Debian 9.0 and 9.8

Still not working unfortunately. I tried on AWS, GCP and Bare metal servers. Port 53 is a no go.
