I know FTP requires two different connections, but I’m confused by the difference between “connection state: related” and “connection type: ftp” in Winbox. What are their differences? Would I need to set up both to enable FTP connections through the router?
Anybody?
Just accept ftp and related connections…
related - a packet which is related to, but not part of an existing connection, such as ICMP errors or a packet which begins FTP data connection (the later requires enabled FTP connection tracking helper under /ip firewall service-port)
connection-type (ftp | gre | h323 | irc | mms | pptp | quake3 | tftp) - matches packets from related connections based on information from their connection tracking helpers. A relevant connection helper must be enabled under /ip firewall service-port
To me this means you can use ‘related’ to catch extra stuff other than just the protocol itself, ie ICMP. It sounds like ‘related’ looks at things not necessarily being used with helpers ) whereas the connection-type only deals with those helpers.
Same as having 4 doors on a car, you can use any of them if you want, obviouslly one might be better than the other depending on where you need to sit.
