2nd Router (DD-WRT) VPN - Help?

[Hyper]

Hi All,

I am wondering if you guys can give me some help with this one as I was trying for several hours last night to get this working with no joy. The setup i have is as follows;

BT Homehub 5 (FTTC Main Router) >>> (LAN Port to LAN Port) >>> TP Link WDR4300 with DD-WRT Firmware (2nd Router).

I have configured the Homehub to use the range 192.168.1.1 with a subnet of 255.255.255.0 and a DHCP range of 192.168.1.64 to 192.168.1.253.

Basically all I want to do is connect the TP Link via a network cable and have it running OpenVPN so I can connect certain devices round the house to its wifi and be running over a VPN. I just need some advice if this is even possible and what would be the best way to configure it?

Not sure if I should be connecting Homehub LAN to TP Link LAN or TP Link WAN to start off, should i leave DHCP disabled and run the TP Link in the same range as the Homehub?

I have tried all sorts of combinations and OpenVPN either doesn't connect or any connected devices still show my Homehubs public IP?

Any help will be greatly appreciated.

Thanks, Sam.

I think you'll need to connect the TP-Link WAN port to a HH5 LAN port. The TP-Link will need to be running on a different subnet. You'll have a double NAT situation, but that only matters under some circumstances.

If you connect them LAN to LAN the TP-Link is basically just going to act as a switch and the traffic will exit directly via the default gateway (HH5).

Running a VPN server or client? What are you trying to achieve?
