Problem with VPN IP leak, Firewall script

[Panhan]

Hello
I have a problem with VPN settings . Here is my previous topic https://www.snbforums.com/threads/openvpn-configuration-ip-leak.50334/

I used the way with jffs firewall script, to block wan . And it seemed to me that everything was ok, but lately i had power outage, so the router and computers have turned off. But when power come back, I immediately connected to the router and found that the computer connected to internet via wan, without vpn for like few seconds, and then go via vpn.


In /jffs/scripts/ i opened file firewall-start and paste there exactly this:

iptables -D FORWARD -i br0  -s 192.168.1.6,192.168.1.33,192.168.1.16 -o $(nvram get wan0_ifname) -j DROP

iptables -I FORWARD -i br0  -s 192.168.1.6,192.168.1.33,192.168.1.16 -o $(nvram get wan0_ifname) -j DROP

Why did this happen? Maybe I have set up something wrong?

Why did you create a separate thread for this rather than continuing the previous one?

If your firewall-start script contains only those lines then it won't have been running at all. The first line of the script needs to be:

#!/bin/sh

The file also needs to be executable and in Unix format, not DOS/Windows.

But when power come back, I immediately connected to the router and found that the computer connected to internet via wan, without vpn for like few seconds, and then go via vpn.

Why is this a problem? It takes 30 seconds or so for all the different components of the router to initialise, so this doesn't sound surprising.
