PPTP VPN Server on 2nd Router

[pauluea]

Hello,

I wonder if somebody could please tell me where I'm going wrong.

I have two routers. An ISP supplied router/ADSL modem which connects to the internet and the ASUS RT-N66U running ASUSWRT (latest version) as a second router. The ISP router has LAN IP address 192.168.1.254 and the N66u has the address 192.168.1.1. They work fine and clients can connect to either router and access file shares from the whole network.

The problem starts when I activate a VPN server on the N66U. I can connect to it but cannot access the internet or browse the local network. I have the N66U setup to assign addresses in the range 10.10.10.1 - 10.10.10.10.

I have fowarded port 1723 to 192.168.1.1.

I'm obviously missing something but and wondered if somebody could point me in the right direction.

Many thanks

Paul
