I thought I understood how this firewall worked, but I can’t get ftp traffic to pass so I obviously do not
Server is at home sitting on a cable modem, has Serv-U ftp server running on port 21. This is also the machine I installed Comodo on.
At work, I fire up the dos based ftp client and try to connect to my server at home, I can see it deny the ftp request in the Comodo log from my work ip address and it shows TCP and port 21. It shows that it is blocking it because of Rule 8, which is the default block rule at the bottom on my list.
Ok, I go into the rule and create a new one to allow ftp traffic.
Action = Allow
Protocol = TCP or UDP
Direction = In/Out
Source IP = Any
Dest IP = Any
Source Port = 21
Dest Port = 21
Save the rule and move it to the top so the default block one is at the bottom again.
try to connect from work and it still block it via the standard block rule…
If I shut off Comodo (Right click try icon and choose exit), I can connect via ftp fine.
Am I missing something here? It seems like the rule I made is being overrided by the default block rule, but from what I’ve read here it goes from the top down and if a top rule allows a hole in the firewall than the default block rule at the bottom won’t override it?
