Hi folks!
I have a old HP desktop that I have set up with Proxmox, and I have a Debian vm running on it that I would like to access through FTP. I have set up vsftpd and it works well on the internal network, but would like to set it up so it is available on any network. I have a static IP.
Because of how my network setup is I am having some problems, and hope someone here might have some guidance.
I have a UniFi UXG-PRO. This is set up behind a TP link router and the ISP router (not optimal I know). This was done since the UXG could not get online directly behind the ISP router due to reasons only the ISP knows and refuses to tell me.
Within the ISP router I have set up port forwarding to the UXG, and in the UXG I have port forwarding to the ftp server. Is this the correct way to do this within my setup?
The ISP and UXG router are both on x.x.1.x, and the TPLink is on x.x.0.x if it matters. I am not able to reach the server from the ISP router network, only the UXG, even with port forwarding enabled. Firewall on the server is set to allow ftp connections on port 21
You really don’t want to do this. Read up on how ftp uses random ports and is not really secure and you will quickly change your mind. A good alternative is SFTP, part of SSH. It uses the same port and is much more secure.
