Yes Tom, unfortunately sometimes it seems that ITKE members are more interested in the problem resolution than the OP.

Using telnet is one way to see if connections work from one host to another. It doesn’t necessarily give a meaningful connection, but it can often provide valuable diagnostic information. For the ftp port, it can often show if the ftp welcome banner is displayed or if the connection attempt times out or if the connection is rejected or…? Whatever the result is, it can help put diagnostics on the right track.

A firewall might block access to a port or traffic from or to various IP addresses or subnets or it might block protocols or…? Without tests, it’s hard to know what direction to take. A firewall can be hardware or software. It could even be the Packet Rules “firewall” on the AS/400 itself.

Of course, we don’t even know what happens when ftp is tried from the AS/400. Error message? Connection refused? Timed out? Unknown host? All we know so far is “…not from my iseries machine.”

Yes, a firewall could be blocking based on IP address, but not the Windows firewall. It doesn’t have such functionality.

It can connect from other PC…

That should indicate that the Windows firewall isn’t doing it. However, it is indeed possible. A software firewall might be blocking based on IP address.

Turnoff windows firewall on the PC and see if that improves the situation.
