What is your command?

For example, mine is:

# sever
/usr/sbin/minivtun -l 0.0.0.0:555 -a 172.16.0.1/24 -e password

# client
/usr/sbin/minivtun -r 88.88.88.88:555 -a 172.16.0.3/24 -e password

if you execute this command in client side, you should see the ping echo.

ping 172.16.0.1

Please check your command.

I used your linux-server and linux-client scripts. And 172.16.0.1 is the server with NAT set up. So I can ping 172.16.0.1 and 8.8.8.8 from 172.16.0.3. Running mtr 8.8.8.8 on 172.16.0.3 also seemed OK.

But running wget https://google.com/ gives me the error above. Basically I cloud not get any TCP/UDP traffic through the NAT on the server. Oddly though, I can correctly get ICMP through as demonstrated in the mtr and ping test.

Do you want to take a look at my run.sh settings o both the server end and client end?

Sorry I am not the author of minivtun and have no idea on it. I even don't know how minivtun works. I just make a openwrt version here.

I can not reproduce your problem according to your description.
