Opening port from server to the VPN Network

[mahesh18]

                   Hi Everyone,

I need to open port 4444 from server to the VPN network.

Where VPN firewall is external .

Need to know the traffic flow here.

If someone access the company network  from home the traffic flow is via VPN firewall to the server right?

Regards

Hi,

So you are saying that you hve an actual firewall and a separate VPN device?

And you want to allow VPN users to contact the server with destination port 4444?

Then you naturally have to make sure that the VPN configurations make it possible for them to connect to the server IP while they are connected. Since we dont know if you are talking about a Full Tunnel VPN or Split Tunnel VPN. In Split Tunnel VPN case you would have to make sure the VPN configurations make this possible also.

Then you naturally have to check if there is any ACLs on the VPN device that requires you to allow the traffic to the server. You might also have to take into account routing unless the VPN device already has a route towards this server.

And then theres naturally the configurations on your actual firewall that need to be checked.

But if I understood correctly the traffic flow is from the VPN Client user through the VPN, through the VPN device, through your firewall to the actual server.
