Hi all,

When I try to connect to my IIS FTP site over LAN I get

200 ...
500 'POPORT 192,168,1,1,19,138' Command not understood
500 ...

I sure the command should be 'PORT 192,...'

This happens on several XP boxes (SP1 and SP2) when
using IE6 and also intermittently when using WS FTP Pro.

What is the deal????

Thanks.

You're quite right, the correct command is PORT. Stuttering like this is
usually a sign that you have a NAT router between the client and server, and
that NAT has not correctly translated the stream of FTP commands and
responses. Report it to the maker of your NAT router, and see if they have
a firmware upgrade for you, or can work on one to fix this problem.

Alun.
