Hi Sebastian,
You've gone about this all wrong; you can't use a "custom" protocol
definition for FTP; one already exists and is part of the FTP
application filter. Delete this custom rule and use the predefined FTP
protocol.

Onderwerp: [isalist] outgoing client ftp problem through isa 2000
http://www.ISAserver.org
Server : 2003, ISA 2000 including all service packs
Clients : Windows XP, no firewall enabled.
I am trying but failing in giving users rights for the FTP Protocol, to
access FTP Servers.
What is the situation :
Client Machines with internet explorer proxy settings enabled, all at
port 8080.
Clients have a default gateway pointing to the ISA server (ISA 2000)
On the ISA server, i made a new protocol definition : "ftp outbound"
port 21, outbound. No secondary connections.
A new protocol rule is made, groups are allowed to used this FTP
OUTBOUND protocol definition.
Outgoing web requests :
"Same listener for all internal IP Addresses", tcp port 8080 and
integrated authentication is used.
"Ask unauthenticated users for authentication" is turned off, this is
because we have a small application running that can't be used with the
firewall client, so it needs just a securenat configuration.
The FTP Access filter is enabled.
The problem :
1. User's can not access ftp sites, i've set the "passive ftp" option in
Internet Explorer but it just won't work.
I tried to set the proxy port in Internet Explorer to 21 in stead of
8080. No result.
2. Then i tried to install the firewall client, now client CAN use FTP
connections.
But i want only the Internet Explorer proxy settings to be used.
Has anyone a clue why my FTP setup won't work without firewall client
enabled ??
Thanks in advance,
Sebastian van Dijk
