Just did a port scan of my computer (via my wag310g router) and was surprised to see port 21 as open. I double checked all of my settings and couldn't see any reason for it to be open.
Looking through the router settings for Single Port Forwarding, Port Range Forwarding, DMZ and Port Range Triggering I could not see any reason for it to be shown as open. I did another scan and checked the logs and couldn't see any dropped entries as I would have expected.
I then decided to forward port 21 to a non existent computer and do another scan, nope still getting an answer to the scan (which means it wouldn't work if I did actually want to run a ftp server as it is going to this "ghost server").
I decided to telnet to my router on port 21 and discovered that it has it's own ftp server that appears to be accessible to the internet.
Here's part of the connect string returned from the router.
"220 WAG310G CPE Batch Provision Tool v1.0 SN(SQL00JA00032), MAC(00:nn:nn:nn:nn:nn)"
So, does anyone know how to stop this server from being globally accessible?
