GS105Ev2 Setting up port forwarding
I just purchased a GS105Ev2 managed switch and I need to setup port forwarding for Http (80), ssh(22), ftp (21), sftp(23), MySQL (3306), and passive ftp. I have tried to figure out how to do it but after a couple of days, I am throwing in the towel on figuring it out on my own. Can anyone help me so I can finish configuring the switch?
Thank you in advance,
Lokirobert
Hi lokirobert
The GS105E is a plain L2 switch, allowing very basic management only. Like almost (when I'm right all) Netgear switches (even those supporting L3 routing) there is no IPv4 NAT port forwarding, mapping, .... - these are Ethernet switches, in no way routers and security appliances. Afraid, you have to re-think your network of there is no router with IPv4 NAT port forwarding in the set-up..
Specifically for ftp (even if using passive ftp) there is more than just port 21/TCP (the FTP control port) required. You have to know the exact port range the ftp server does use in passive mode. While a "smart" router might be able to work with plain text ftp (thanks to what is called an FTP-ALG), things will fail when you start using ftpes (the only thing you should do over the wild Internet anyway) and you have to forward the passive port range manually to the FTP server LAN IP.
