Hello!

I need help with setting up a VPN connection between to hosts where the client is behind a firewall.

My setup looks something like this:


WinXP ---- Firewall --- internet ---- linuxbox

I also have a linux box inside the firewall if that helps the setup could be like:

WinXP ---- Linuxbox --- firewall ---- internet --- linuxbox

The problem is that i want to be able to run World of Warcraft, (gamer yes) on the WinXP machine which is located behind the firewall.

I need access to TCP port 3724, 6112 and 6881 through 6999, both incoming and outgoing connections.

I don not have any possibilities to change the firewall configuration, so i thought that a VPN connection would do it.

I managed to set up a ppp-ssh connection between the two linuxboxes.

But PPTP failed. seems like the firewall is blocking ports needed for pptp.

Is ppp-ssh the only possibility for me?
Or is there a way to force PPTP to use some other port than 1723?

suggestions?

thanks for help!

Hi,

you can use VPN, if the firewall doesn't block port.
you can also use a ssh tunnel: see http://www.hackinglinuxexposed.com/articles/ and have a look to the SSH Tunneling articles.
Ssh tunnels would be set up between the 2 linux boxes, it's more simple to set up but I don't know whether the performances will be there.... but as most of time, you'll be limited anyway by internet and not by the Linux boxes.

Hi friends

Need a small solution. I have set up a Linux MAIL server with a Static Public IP.

LinuxServer with >>> REMOTE CLIENTS (Present solution)
static Public (MS-PPTP-IPSEC+Static
IP (VPN+PPTP_IPSEC) Public IP)



Needed Solution on the present setup

LinuxServer with >>> REMOTE CLIENTS
static Public (MS-PPTP-IPSEC+Static
IP (VPN+PPTP_IPSEC) Public IP)

>>> REMOTE CLIENTS
(MS-PPTP-IPSEC-DYNAMIC Public IP)

Ports opened so far.... 25,110,1723-TCP
47 GRE

A firestarter firewall is installed on the Linux Mail server.On disabling the Firestarter firewall the Remote client with Dynamic public IP connects to the
mail server and retrives and sends emails. But on switching the firestarter on,it just says connecting and times out.

I need a solution for this.Do i have to increase the TTL on the VPN so as to enable it more time to connect. Is the firewall not allowing or slowing down the connection process.
