Once on the VPN you can connect to other nodes without port forwarding because every node on the VPN, like on a LAN, has a unique local address.

Which gets to your question, "Isn't the point of a VPN to not have the need to port forward?".

This is not much good outside the LAN, however, unless you can connect to it from there (the outside), which requires your router forward the traffic to the appropriate place, which is port number based, hence, port forwarding. If you don't want to use an external server, then you must have one inside the LAN. Your local computers connect to the VPN via that server (on the appropriate port). But if something outside your LAN wants to initiate a connection to something inside your LAN, it must to use the external router address, and, unless you've set up port forwarding, the router will not know what to do with that.Īlternately, if you use a VPN server outside your LAN, either one you set up yourself (~$5-10 USD a month depending on traffic, but this assumes technical expertise) or one you pay someone else to use (many VPN services are of this sort), then you don't need port forwarding. Port forwarding only works if it forward from 1194 -> 1194. Yes, but using a port other than 1194 for external access doesnt seem to work. Traffic wrote: OpenVPN supports practically any port you like (there may be some restrictions from other sources).

That works because all the connections established between those computers and the outside world are initiated by the local computer, not the outside party, meaning the correct MAC address is associated with them. Re: OpenVPN and router NAT (port forwarding) Post. This does not require port forwarding because they can be distinguished by MAC address. 1 LAN IP addresses are considered local all the computers on your LAN use the same IP address externally.

What you need port forwarding for on your router is to allow incoming connections to a node inside your LAN. Setup Port Forwarding for user1 find/replace YourVPSIPHere with your server/VPS IP. That said, not you do not need to use port forwarding to use openVPN. You need the internet, and the internet uses port numbers. So: It is impossible to do much of anything on an IP network without using ports. ie., pretty much everything most people consider "networking") includes a port that is essentially part of the address in the same way that your street number is an essential part of your address. What?Īny and all IP network communication (read, anything that involves IPv4/6 addresses, hostnames, etc. No, you do not have to use port forwarding, but a port number is still intrinsic to the process.
