![]() ![]() IF that client is behind a nat - the router needs to forward that traffic - normally it does this through helper service for ftp, etc.īut without seeing your logs of your connections its hard to know where your problem is.Įdit: Another thing I would do is verify all the modes you want to use are working from a local machine connecting to the local IP of the server. Now keep in mind you can have nat on both sides that could cause problems - even with a active connection - the server is creating the connection from source port 20 to the client. ![]() ![]() These commands are sent through the control channel - so if your control channel is encrypted - option when using FTPS then the helper might not be able to change the private IP to the public one, nor will it be able to read the port it needs to open. Is it the public IP - what port, is that port forwarded on your router! Please post up the logs of your connection from the client - on the pasv connect you need to look to see what the client is seeing. being told to connect to private IP would be pointless, and does the nat router on the server side forward port 3570 to the server? The ftp server tells the client to connect to it its 192.168.1.99 on port 13*256+242 or 3570 So this is active connection to ftp on my local network. So for example when connecting to a ftp server in active mode you see this. Without actually looking at it, or even seeing the logs - can you post up the log from your client. And then you have to take into account possible nat on the client side as well.ĭid you read the article I linked to that explains how ftp passive and active work - this will give you info to troubleshoot your problem. And you would have to make sure the ftp server hands out the public IP vs its local IP.Īgain the way that the ftp protocol works can be a bit of a pain to have it work through nat, etc. You state active ftp works, does passive? If you router does not have a helper or broken - then you would need to forward the ports your ftp server would use for passive connections. Its quite possible your nat router does not have a helper or is broken? ![]()
