Hello everyone
I need some help with VPN settings.
I have 1 CableModem (ISP) with DHCP server, 1 Belkin as AP for Wireless and 1 TP-WR841N v10.

Cable Modem (Router & DHCP server)
LAN IP: 192.168.1.1
MASK: 255.255.255.0
Gateway: 192.168.1.1
DHCP Server: 192.168.1.1
DNS1 (ISP): 213.228.128.*
DNS2 (ISP): 213.228.128.*

Portforward:
IN 22 - OUT 22 for 192.168.1.253 for TP-WR841N v10 (SSHd) - WORKING
IN 80 - OUT 80 for 192.168.1.1 ISP Cablemodem - WORKING
IN 80 - OUT 8090 for 192.168.1.253 for TP-WR841N v10 (DD-WRT) - WORKING

IN 47 - OUT 47 for 192.168.1.253 for TP-WR841N v10 (DD-WRT) - UNSURE
IN 1723 - OUT 1723 for 192.168.1.253 for TP-WR841N v10 (DD-WRT) - NOT WORKING

Belkin (Configured for AP) with RJ45 connection to cablemodem.
LAN IP: 192.168.1.254
Mask: 255.255.255.0

Everything working fine.

Now:
I have plus one more router (TP-LINK WR841N v10) with DD-WRT: DD-WRT v3.0-r28882 std (01/19/16) configured as Router with the following configuration:

Connected to cable modem via RJ45 at WAN Port with Assign WAN Port to Switch.

WAN: disable
LAN IP: 192.168.1.253
MASK: 255.255.255.0
DNS: 192.168.1.1

DHCP: Forward
DNS Server: 192.168.1.1

Operation Mode: Router

PPTP Server Enable
Server IP: 192.168.1.253
Client IP: 10.10.10.1-5

PPTP working from inside LAN.
PPTP not working from WAN: always saying the connection was interrupted or error 807.

Any solutions for this or is there any mismatch configuration i've not made correct

Thank you
