HELP: PPTP server on OpenWrt - cannot access the router from the VPN client

Installing and Using OpenWrt Network and Wireless Configuration
1

Hello,
I recently switched to a banana-pi bpi-r3 router.
I installed the latest snapshot image and configured PPTP server according to https://openwrt.org/docs/guide-user/services/vpn/pptp/server.

I can connect from a remote machine and after issuing the command nft insert rule inet fw4 forward iifname "ppp\*" counter accept, I can access all my local LAN IPs except the router itself:

    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),

My /etc/config/pptpd configuration is like this:

config service 'pptpd'
        option 'enabled' '1'
        option 'localip' '192.168.18.254'
        option 'remoteip' '192.168.18.250-253'

config 'login'
        option 'username' 'user1'
        option 'password' 'pass123'

On OpenWrt v22.03.3 (although an a different hardware) it was working fine.

Please advise.

Although my question will not directly lead to a solution here, is there a reason that you've chosen PPTP? This protocol is not secure and is specifically considered unsuitable for use on the modern internet. It has been deprecated and removed from many operating systems (for example support was removed from iOS and MacOS maybe 6+ years ago).

I would highly recommend another protocol such as Wireguard or even OpenVPN.

I know that but I need a client-less VPN solution

What do you mean by this? What is the remote endpoint?

Using the built-in windows options for the client.
The the remote endpoint if the OpenWrt router of-course.

Windows still includes PPTP? Wow!
Is it not possible to install WireGuard on your windows computer?

Sadly I cannot install WireGuard.

That's really unfortunate. Just keep in mind that PPTP is only marginally safer than no encryption and direct exposure to the internet.

I stopped using PPTP many years ago and I don't remember any of the details of the configuration, so I cannot help you resolve issues.
