If the server is directly connected to the Internet, rather than being behind NAT, see this blog post. Where applicable, services such as Mail must be configured to listen on the netblock assigned to VPN clients.ДЁ. To make services accessible through the tunnel, you need a working DNS service. Bonjour will not work over an L2TP or PPTP VPN. It must be disabled both on the server and on an AirPort router, if applicable.Д§. 'Back to My Mac' is incompatible with the VPN service. To lessen the chance of such conflicts, it's best to assign addresses in a random sub-block of 10.0.0.0./0 with a 24-bit netmask.Д¦. For example, if the endpoint assigns addresses in the 10.0.0.0/24 range, and the client has an address on a local network in the 10.0.1.0/24 range, that's OK, but if the local network is 10.0.1.0/16, there will be a conflict. Each client must have an address on a netblock that doesn't overlap the one assigned by the VPN endpoint. If yours is doing that, you won't be able to set up a VPN.ДҐ. Some residential ISP's block incoming UDP packets statefully. Otherwise, something in the network is blocking some of the required traffic. If you've taken all the above steps, the Server app should show that the VPN service is accessible from the Internet at your external IP address. Configure any firewall in use to pass this traffic. There may be a similar setting on a third-party router.Д¤. If it's not already checked, and save the change. In the sheet that opens, check the box marked If your router is an Apple device, select the Network tab in AirPort Utility and click Network Options. The Server app can set this up for you if you have an Apple router. Forward external UDP ports 500, 1701, and 4500 (for L2TP) and TCP port 1723 (for PPTP) to the corresponding ports on the VPN server. Give the VPN server a static address on the local network, and a hostname that is not in the top-level domain 'local' (which is reserved for Bonjour.)ДЈ. Also in the latter case, you must run a background process to keep the DNS record up to date when your IP address changes.Дў. The latter must be a DNS record on a public DNS registrar, not on the server itself. Give the gateway either a static external address or a dynamic DNS name. To run a public VPN server behind an NAT gateway, you need to do the following:ДЎ. Loading plugin /System/Library/Extensions/L2TP.ppp Shouldn't port 500,1701, 1723, 4500 be visible in internal portscan or external site check (Every time I try to connect VPN from my iPhone on 4G-network, the server log shows something like:

My server's websites are reachable over intenret (port 80 and 443). The port forwarding is working on my router.

I've configured VPN service on Mac OS Server 5.0 but the VPN ports (UDP 500, 1701, 4500 and TCP 1723) are not reachable over internet or local network.
