VPN server one nic

[Guest MarcusB]

Hi,

We have all our servers behind the firewall, all clients are on the

other side of the firewall and are secured from the internet by

additional firewall which blocks Windows file sharing etc. We want make

posible for our coworkers to access our fileservers and other services

from home.

Can we configure server to be vpn server with one nic card? We will

open than ports in the firewall only to this server. What port should we

open than?

Re: VPN server one nic

 

Yes, you can run a server on the LAN with one NIC as a VPN server. You

can test it by connecting to it from another LAN machine using its local

name or LAN IP.

 

To connect to it from a external machine you will need to connect to the

firewall's public interface. You can use port forwarding to extend the

connection to the VPN server on the LAN. What port (s) you need depends on

the type of VPN you set up. For a PPTP VPN you need TCP port 1723 . You also

need to ensure that your firewall does not block GRE. This is IP protocol

47. Note it is a protocol, not a port! The encrypted data has a GRE header,

so no data will cross the VPN if GRE is blocked at the firewall.
