DNS and iptables problem with Windscribe VPN connection

Hi guys
I install Windscribe VPN GUI latest version from site arch package. then I can successfully connect but I Firefox or browser can't web browsing...
I try to get ping 4.2.2.4 and it's done, but when I wanna get ping google.com. I can't do this...
so I think the problem is DNS and iptables...beacause I check /etc/resolve.conf and after connect to VPN then nameserver 10.255.255.3 is top and everything is OK...

so I check iptables with: I run:
`sudo iptables -nvL --line-numbers`
to show my chains and rules. in next step I look for windscribe_dnsleaks chain and I think the problem is here.
next. I run:
`cat /etc/resolve.conf`
in windscribe_dnsleaks chain part I saw ip of nameserver of VPN is drop and the target is drop!!!!

so I delete this rule with:
`sudo iptables -D windscribe_dnsleaks 1`  #  (1 is line number)

and that's work's temporarily fine. I  add the rule to allow port 53 for DNS and both protocol udp and tcp to iptables rules:

`sudo iptables -A windscribe_dnsleaks -s 10.255.255.3 -p tcp --dport 53 -j ACCEPT`
`sudo iptables -A windscribe_dnsleaks -s 10.255.255.3 -p udp --dport 53 -j ACCEPT`

and finally save it :
`sudo iptables-save -f /etc/iptables/iptables.rules`

and surprisingly that's work and I can connect to internet with my Windscribe VPN...

but after reboot  the problem is come back and I check everything in iptables is OK:)))) anyone have idea???
tnx a lot;)
(((oh I also change ip_forward to 1 to Linux acts as router with: `sudo sysctl -w net.ipv4.ip_forward=1`. I don't know this is nessasery or useless action...

I'm in the 6.1.71-1-MANJARO
