Time Capsule Does Not Port Forward FTP Ports
Hey there,
I recently purchased a Time Capsule, and I found out that while it fixes the NAT-PMP bug found in my previous AirPort Extreme Base Station (Gigabit-N), it introduces a new problem which makes it refuse to forward port 21 properly.
It seems to me that the Time Capsule has some sort of FTP server built in, and is either enabled but closes connection on client connection, or disabled but still listens for client connection.
This message is what I get when I connect to my IP via FTP from the WAN side (FTP port forwarded to a local machine with an IP 10.0.0.8):
421 Service not available, remote server has closed connection.
When it is accessed from the LAN of course, I can connect to 10.0.0.8 with no problem. However, what is interesting is if I connect to the Time Capsule via FTP I get this as well:
421 Service not available, remote server has closed connection.
Thus, I am 100% certain that the FTP message I see when I connect from WAN is from the Time Capsule instead of the machine I port forwarded to.
Apple needs to fix this annoying problem and at the same time fixes some VPN issues I'm having with my Nortel VPN client (4.68). It was all working when I had the AirPort Extreme Base Station.
