Hi Francesco,
Do you know about some ADSL Router that works fine with that?
I would like to buy it.
How does it cost?
Do you have any experience with this type of connections?

Thanks about your help!

With ADSL router it should works fine.

You can verify if the GRE protocol (protocol #47) is forwarded. Expecially,
try to look if there are some firewall restrictions; usually some
connectivity supplier put on their adsl routers some blocking filters.

Subject: [pptp-server] PPTP Connection over NAT

Hi all,
I'd like to know if is possible to stablish a pptp connection over a nat.
Let me explain:
I have, at home, a simple ADSL modem (Ericsson HM220dp) and would like to connect to our VPNServer (with a real address) in the office to access my office network.
This modem does simple NAT, so I have a fake address (right now it's - the modem has and when I try to connect to my VPN Server, it stays Verifying Username and password, and nothing happens. I'd like to know if there is some way to connect to my VPNServer even when I have a fake address and are doing NAT to navigate. All works fine with this modem (send/receive files in mIRC/ICQ/MSN - yes I have Winblows @ home).
Can anyone helps me?
