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.
Does it minimally work from the PPTP client side? IOW, is it only a routing problem on the PPTP server side?
P.S. Unfortunately you can’t always trust the wiki's/guides. They're often old, have errors, or things just change underneath them making them obsolete. FWIW, I made a quick scan and it *appears* to be right. As you can imagine w/ these things, all you have to do is make the slightly error and things don’t work. And that makes it really hard to diagnose, esp. for someone else.
Also, realize, you *could* setup a VPN server and client on each router as an alternative. It ends up giving you the same results. And it avoids having to deal w/ the routing manually. That's really all this config is doing; saving you the trouble of duplicating VPN servers and clients. The config proposed in that wiki also means the VPN can only be established in one direction. That *may* be a disadvantage in some situations!
I've seen a lot of ppl having problems w/ dd-wrt’s PPTP implementation lately, and I'm not sure why. I helped a guy only a few days ago with similar problems. After examining my PPTP server (running on a tomato router) and his, I noticed some differences and gave him some iptables changes (for the PPTP server side) that seemed to work.

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.
