Cannot map same IP address into multiple ports on Liferay PaaS VPN

Note: please note that Liferay has renamed its Liferay Experience Could offerings to Liferay SaaS (formerly LXC) and Liferay PaaS (formerly LXC-SM).

Issue

You have mapped the same IP address to multiple ports on Liferay PaaS VPN configuration but it is not working the connection.

Environment

Liferay PaaS
VPN Connected

Resolution

If you are using the same IP address and different ports mapped into different Liferay PaaS ports such as:
```
192.168.0.0:8080 mapped to VPN:8080

192.168.0.0:9090 mapped to VPN:9090

192.168.0.0:7070 mapped to VPN:7070
```
We are currently developing an improvement so this scenario can be possible. But, for now, you can not map the same IP even using different ports.
If you are using the same combination IP address and port to map into different Liferay PaaS VPN ports such as:
```
192.168.0.0:8080 mapped to VPN:8080

192.168.0.0:8080 mapped to VPN:9090
```
This scenario is not possible. Each combination (IP address + private port) can only be mapped into a single Liferay PaaS VPN port.
