OpenWrt Luci pptp client VPN Configuration

Installing and Using OpenWrt
1

I'm switching routed, the current one uses DD-WRT the new one uses OPENWRT.
I set up the VPN on the new router following the https://openwrt.org/docs/guide-user/services/vpn/pptp/client documentation

But it does not work, presents the following error: NEGOTIATION_FAILD.

Can they help solve the problem?

Please, specify, which device you are running client and server. The same issue is discussed here: After upgraded to 18.06.4 I have to add firewall.user for using PPtP VPN

  • tp-link 840N router
  • OpenWRT Luci
  • I installed the client pptp
  • VPN server: Private Internet Access

Note: It works on another TP-Link router using DD-WRT, but the new router doesn't support it, so it's trying to configure OpenWRT. I followed the script from the link below but got the NEGOTIATION_FAILED error.

44/5000

All suggested packages were installer

I recommend you to use OpenVPN, I can help you, if you wish.

Thanks for the support
I will check if my equipment supports, I believe not.

My TP-Link WR840N device does not support OpenVPN due to low memory.

I believe it will be easier now to help me.

I reviewed the installation and everything is correct except the instruction below that I can't write.

I use putty

the 1st line has access denied
the 2nd line is accepted and the VPN starts working, but when I restart the router the VPN stops working.

How to do to fix the instruction?

root@OpenWrt:~# /etc/firewall.user
-ash: /etc/firewall.user: Permission denied

root@OpenWrt:~# iptables -t raw -A OUTPUT -p tcp -m tcp --dport 1723 -j CT --helper pptp

You are trying to "run" /etc/firewall.user instead of editing it:

vi /etc/firewall.user
