Blocked Port 21
I need port 21 for my freelance job which i'm doing from home. the company i have a contract with uses ftp servers with port 21. is there a way to get telus to unblock port 21 specifically or do I ha...
You will need to set up your router and the FTP client to use non standard ports, Telus blocks most of the known ones.
When i had a FTP server running locally on the fibre a few years ago it was necessary to set port forwarding on a third party router (PfSense) and have it connecting through a port that Telus wasn't blocking, think it was port 8081 I used. Had no issues with it, as a bonus you can set up a dynamic DNS service as well on the router so you don't need to keep changing the IP address when you get a new DHCP lease.
As Nighthawk mentioned the standard FTP isn't the most secure. If there is only one user or a handful of them connecting to the server, it may be wise to add a Whitelist of their IP addresses on the firewall as well, blocking anyone else that isn't on that list from hitting your FTP server.
Note that most all residential providers do this to some extent. You mentioned looking into another ISP, beware any mobile ISP's or Starlink which use CGNAT.. this makes even the above process impossible, forcing you to pay for the business plan which is considerably more expensive.
