Hi,
I have a rather tricky problem here: one of my friends recently set up
an ISA server and now tries to publish an FTP server on a second server.
I searched all over the net for posts regarding the trickyness of FTP
server publishing but didn't find anything else than the special
requirements for running FTP on the ISA itself.
Here's some sample IPP log:
2002-08-12 19:25:40 217.82.196.212 80.142.136.69 Tcp
8414 21 BLOCKED Dialout
2002-08-12 19:25:43 217.82.196.212 80.142.136.69 Tcp
8414 21 BLOCKED Dialout
2002-08-12 19:25:49 217.82.196.212 80.142.136.69 Tcp
8414 21 BLOCKED Dialout
2002-08-12 20:28:35 217.82.196.212 80.142.133.13 Tcp
8797 21 BLOCKED Dialout
2002-08-12 20:28:36 217.82.196.212 80.142.133.13 Tcp
8797 21 BLOCKED Dialout
The first address being me (also behind ISA) trying to connect to the
published FTP service.
My FTP clients either get a timeout or in case of Windows 2000 ftp.exe
an 'unknown error'
So this raises three questions:
1. could it be that FTP is one of those protocol that do not work well
if both parties are behind a firewall?
2. why do I have a blocking from a packet filter, when to my
understanding publishing the server should suffice?
3. What can we do to get this setup working?
Thanks for your help!
Mark
