So i followed these instructions here near perfectly and i am not able to ping anything on the other network.

http://www.dd-wrt.com/wiki/index.php/Point-to-Point_PPTP_Tunneling_with_two_DD-WRT

when i go to the STATUS-LAN page on the router that is acting as the PPTP server i can see my client connection from the Client Router. I would assume that means that the PPTP connection is working proerly, but the routing is not.

I set up the static routes, but no luck. Does this guide work for anyone else? I would think this is a pretty common thing to do, but from looking around there doesnt seem to be a definite solution.

Any help would be greatly appreciated.

Thanks

I cant seem to get to anything from the client side. I haven't really tested from the server side to the client because i am not there.

When i look at the "Connected PPTP Clients" at the bottom of the LAN Page this is what is see.



pppo - [MySecretUsername] - 192.168.2.1 - [RemoteIP]

the 192.168.2.1 address is actually the local IP address of the client router. The Router IP is The WAN Address of the client router. is that right?

I personally like PPTP only for a single host connecting to network,

IPSEC or OpenVPN for subnet to subnet.

Correct

Easiest way to think of a subnet is a group of addresses.

You may want to give OpenVPN a try.

I am looking at OpenVPN. One of the router's is a Asus RT-N12B which has -mini installed on it. Is there any way to get OpenVPN on that?

That is NOT correct. You can most certainly have two routers or 100 and one subnet.

Subnet is not necessarily a group of addresses all it does is determine the network and host portions of the addresses and where the IP header and footer start and stop.

It provides the structure for an IP packet.

I too have followed the documentation for a pptp vpn and got it to work nearly perfectly with 1 exception, routing beteen the end points only occurs if the address has been assigned by the dhcp server. My set up is between a main office (vpn server) and a small sales office (vpn client). At the main office i have a file server set up with a static ip on the same subnet as the vpn server. At the sales office all clients receive ip addresses via the dhcp server. The machines at the sales office can get the files off the server, but from the file server, on the vpn server side, i cannot ping any of the machines at the sales office or see the printer which has a web server to monitor consumable usage. At the main office I also have a few clients whose IP address comes from the ddwrt server box and those clients can ping the machines at the sales office and see the printer consumables.. I believe this is a firewall isue but im not sure what needs to be put in the firewall to allow all nodes in the subnet, even those not from the dhcp server, to "see" the other side of the vpn. Any help is appreciated.
