thank you very much. This is exactly what I was looking for if I can deploy OpenVPN.

Your assumption is great, because my modems don't support VPN so I was planning to replace them. If I can do it with any other way I think it is also OK. This way, the open VPN computer should be the default gateway for the network I guess?

Actually, the main intention is managing multiple APs from several different locations. However, any company which can need this solution will probably have an hdlc, ppp etc. connection between the branches. However, for test topology I only have 2 adsl lines and can use 2 modems to simulate the situation. About VPN, I am not sure about OpenVPN but how can I run that software on an ADSL modem? I don't have any server machines in the system. Only 2 adsl modem/routers. I feel I need to establish some kind of point to point communication between the public sides of the modems and they can route the packets to internal networks. Can static routing feature fix this issue?

Hello All, I am trying to set up a demo project and having a problem in one of the basic steps. Here is my set-up : To achieve the desired function in the shown topology, what options do I have? 1. I think a VPN connection between the two DSL modems can resolve the situation. If this is true, what modem should I use to establish a site to site vpn? (cannot afford router devices, it is why I want to use ADSL modem to achieve this) 2. I feel I need to use some type of Point to Point connection between the two system but how is that possible? Since there is no leased line, hdlc or framerealay here (only internet) what can I do? 3. IF I put the AP and AC as DMZ devices in each modem, can they communicate between each other with the real ip numbers? (I am unsure about it) I am really in need of some comments here. Thanks in advance.
