VPN client problem when trying to initiate client connection from behind a firewall
I have set up a vpn server using W2003 RRAS.
I have set up a pptp client on my laptop and I can connect with this if I use a modem connection.
However if I am at a client's office I still need to connect to my network through their system. So if I plug my laptop into their ethernet network I can get a connection the internet but I cannot get to my network using the VPN. It seems that the request gets to my server but the response is lost. I would guess a firewall issue.
I need to have access to my network from anywhere inside or oustside any of my client's firewalls. I do not really want to have to ask them to configure their firewalls to allow responses from my server. Is there a way round this?
Is my understanding of the problem correct? Is it possible to use pptp in this scenario? If not, are any other VPN methods going to give me the functionality I require.
Much obliged

if you have a little money to spend...Cisco offers a WebVPN...this is an application layer VPN solution that works over standard web ports. As far as I can tell I dont see another solution that would meet your needs via VPN. Cisco 3005 VPN concentrators have sold on Ebay for about $1300 but new I think they are about $3000.
There may be other solutions outside of VPN that may work for you. It would depend on what services you are accessing with your VPN.
If data access is the main concern ( ie...email, documents, software access, etc...) then you could run RDP over port 80, 21, or any other common port. This would allow you remotly access a desktop on your network and do what ever you need to do. This assumes that those ports are available on your network.
I think this would be the best solution for what you have described.

So I could use rdp to access my network from somewhere else? How is that setup?

It sounds like your client's office is blocking inbound and outbound connections on certain ports, such as VPN's port. They probably only allow basic services such as internet and email, which use ports 80, 110 and 25 respectively. Without talking to their IT staff, the only way to get around this is to make your own connection to the internet, via dial-up or wireless.
