Please log in for more thread options I've set up in the office a VPN-Server based on Windows Server 2003 and this server has only one network card configured for 10.0.x.x network with 255.255.0.0 subnet. The default gateway for this machine is a Cisco Firewall 10.0.0.101 that supply internet broadband connection. Internal DNS is 10.0.10.0 VPN Server has a pool of static IP addresses for the clients: from 10.0.51.1 to 10.0.51.50 From outside, there's a dedicated IP adress and all connection requests on dedicated PPTP & L2TP ports are routed by the firewall at VPN Server. So, if I try to make a VPN connection from a notebook with a dialup connection all works perfectly: i can see all the LAN in which VPN server is....but....If I try to connect from home i've no connection problem (i can see my connection on server logs) but i can see nothing on office LAN From home I've a ADSL connection and a D-Link DSL 504-Router with this configuration DHCP from 192.168.0.1 to 192.168.0.253 Subnet 255.255.255.0 Ethernet IP Address 192.168.0.254 Proxy DNS enabled NAT enabled --------------------------------------------------------- This is the ipconfig /all result from home Configurazione IP di Windows Host Name . . . . . . . . . . . . . . : xxxxxxxxxx IP Routing enabled. . . . . . . . . : No Proxy WINS enabled . . . . . . . . : No Home LAN: Description . . . . . . . . . . . . . : SiS 900-Based PCI Fast EthernetAdapter DHCP enabled. . . . . . . . . . . . : No IP address. . . . . . . . . . . . . : 192.168.0.1 Subnet mask . . . . . . . . . . . . . : 255.255.255.0 Gateway............ . . . . . . . . . : 192.168.0.254 DNS Server . . . . . . . . . . . . . : 85.38.28.70 VPN: Descrizione . . . . . . . . . . . . . : WAN (PPP/SLIP) Interface DHCP enable. . . . . . . . . . . . : No IP address. . . . . . . . . . . . . : 10.0.51.5 Subnet mask . . . . . . . . . . . . . : 255.255.255.255 Default gateway . . . . . . . . . : 10.0.51.5 DNS Server . . . . . . . . . . . . . : 10.0.10.0 151.99.125.1 ------------------------------------------------------------------- Anyone can help me?

Please log in for more thread options thru? If it works on dial-up and not thru DSL, then it sounds like the router config for your ADSL link is the problem. You may also want to try and hook up your ADSL directly to your laptop and use PPPOE software. This will let you know if your ADSL ISP allows VPN protocols to go over their network. moncho | |||||||||||||

Some DSL providers, although they are far and few between, do not allow

You will need to check your usage agreement with your DSL supplier. If it is one of the big ILEC's, blocked ports on the vendor's network is not your problem. What you want to do is get your router out of the way first to make sure it is not the problem. Did you make sure to allow VPN pass-thru on your router? moncho | |||||||||||||
