Hi,
The issue:
From the WAN, I get timeouts when trying to access the FTP, the HTTP site works just fine
From the DMZ, I have access to the FTP and HTTP no problem (tested from the FE firewall)
From the LAN, I have timeouts as well when acessing the FTP. HTTP still fine.
The error (comming from the back end firewall in the monitor)
0x8007274c WSAETIMEDOUT
My config:
WAN
Front end firewall (TMG on Win 2k8 SP2 x64)
DMZ with IIS7 server
Back end Firewall (ISA 2006 on Win 2k3 R2)
LAN
On the IIS7 server, I have a website and an FTP site and using 2 different IPs in the bindings
I have almost the same publishing rule on both firewalls:
Name: Publish FTP server
Traffic: FTP Server
From: Anywhere
To: IP address of the FTP server in the DMZ
checked request appear to come from the [firewall] computer (tried both settings, same thing)
Networks: External, Internal, local host (for the FE); External, Internal (for the BE)
On the FTP server, in the firewall settings, I can set the external firewall IP or not, same thing.
It has to be something stupid but I just don't see what!?
