Debugging output does not appear when use Debugging IPAddresses

[Schroeder2]

I recently absorbed the task of supporting our CF MX 6.1 server. We have an
app that we need to debug - the developer asked us to add her IP address to the
"Debugging IP Addresses" list. I turned on debugging and added her IP address
to the list, but debugging output is not displaying; this is true even when you
run the CF app on the server running CF. The steps I took are as follows:

- In CF Administrator, checked Enable Robust Exception Information and Enable
Debugging. Submitted changes and got msg Server has been updated successfully.
- Added developer's IP address to the list of debugging IP addresses. She
couldn't see the debug output. Neither could I.
- Restarted CF server. No change.
- Rebooted server box. No change.
- Tried removing all IP addresses from list. Debugging input then shows for
everyone.

Showing the debug info to everyone is not an option, so we need to get the IP
address filtering working. I've looked at the Windows event logs, the CF logs,
and these forums, and can't find any helpful info.

Server config:

Windows Server 2003 (Standard Ed.) SP1
ColdFusion MX 6.1 (6,1,0,63958) Standard

Any suggestions would be very much appreciated.

I figured out the problem - it turns out that even our LAN traffic goes through
our ISA server, and the ISA server passes its IP address to IIS, so CFMX is
seeing all traffic as coming from the same IP address - the LAN address of the
ISA server. Adding that turned it on for everyone, so it seems that the
solution lies in changing the config of the ISA server to pass through IP
addresses. See post by "Smiley Dave" titled "Debug IP Addresses" for a little
more info.
