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.
