Right now I have 2 branches in Asia; one is in Malaysia and another in Vietnam.
Unfortunately both are communicating using port 6901-6999 and port 1433. Because of the long distance between the two I am afraid there will be communication problems so I'm using a VPN to avoid using port forwarding at the router. Can the VPN avoid or pass through the router? Both computer are in same network. I think there is no need to set port forwarding any more, right?
I'm using Ubuntu server to host VPN.
Or is there any method to prevent setting port forwarding in the router?
- Using VPN on both computer, we only setting port on VPN Server. We do not need to set any port forwarding in router, correct or not?
- If #1 is incorrect, do you have any ideas for avoiding port forwarding in the router other than using Hamachi?
