Redlion Crimson FTP

[TigerCR1200]

I have a client who wants to use the FTP server built into the Redion Crimson HMI. I have it set up and can connect to the server when I am behind the router. When I try to connect to the FTP server from outside the router I end up with this error:

Command: SYST

Does anyone have any idea if this is an issue with the FTP Server or the Router or some other random issue I am unaware of?

Looks like it is a network topology issue. If you can access the server from behind the router with an IP address of 192.168.13.XX on your machine but not from outside, e.g. from the internet/corporate network you will need to do some port forwarding or configure a firewall to allow a connection between the networks.

Can you provide some more information about your network setup?

I agree with alexmarcy. If you can connected locally then it seems to be a routing or network issue. There are no settings that can be altered on the red lion side to make it work differently in this situation.

Thanks
