DD-WRT Site-to-Site VPN

Good day experts, I am looking for someone to provide the configuration for  2 Buffalo WZR-1750 routers running v24-sp2 for a site-to-site VPN.

Remote Site: IP Range 192.168.113.0/24
Local Site: IP Range 192.168.13.0/24

I want all traffic from 192.168.113.0/24 to route through the gateway located at 192.168.13.1 which it Nat'd to my cable modem.

I am going on the road for an extended period and want all my traffic to route through my home connection.  I am fairly network savvy but don't have the time to try and figure out all the setup before I depart.  I understand the implications of back-hauling all the traffic, but there are a number very specific reasons I need to do this.

Thanks in advance!

dd-wrt has an example that is now hosted/managed http://wadihzaatar.com/?p=11

The simplest option, would to setup PPTP server on your home router.
Then the one you will be taking with you configure as a PPTP client.
All traffic from your remote router will be sent through your HOME.

Not sure why you would want to waste the bandwidth and the speed since your download on the remote side will be limited by the upload speed of your cable modem.

Sorry I have been out of town.  If using PPTP, what do IP setup for Server IP and Client IP(s).  Can the client be open to any IP (I will not know my remote IP until I arrive)?.  CHAP-Secrets, just setup my own pass phrase?

Thanks so much!

User error ip needs to be another IP on the LAN that is not used.
The client IP will be assigned from the range you include in the config.
The only concern is to make sure the IP on your LAN are not one of a common 192.168.0.0/24 .1.0/24  or .2.0/24 to avoid having an IP overlap.

Dd-wrt.com has other site to site VPN example using openVPN as well.

Setup PPTP, works like a charm.  Router to Router and iPhone/iPad/Android Device to Router.  Thanks
