How to open a port in RV325?

[fsbcomputers]

Hey guys,

I'm looking for a way to open a port (port 43 - whois) in RV325, so I can check if domains are taken for my customers and I don't want to use an external service for this.

I tried using the GUI, telnet and SSH, but I couldn't find it in the GUI and I couldn't connect using Telnet or SSH, I also don't see a console port on it to connect via COM port, so how can I do it?

Thanks.
