Hi Everyone,
It looks as though I'm dealing with a web proxy filter issue. Is there a
way to edit the web proxy filter?
The attached .jpg shows the error..
Error Code: 500 Internal Server Error. The HTTP message includes an
unsupported header or an unsupported combination of headers. (12156)
...when trying to open a .pdf attachment through the firewall. This occurs
with IE and Firefox.
It works FINE when surfing the local private IP address but NOT the public
ipaddress through the firewall.
If I try and unselect the Web Proxy Filter in the HTTP properties for this
rule, it states
This application filter is used by the corresponding protocol at the
enterprise level. Therefore, it cannot be deselected.
I've tried modifying this web publishing rule's properties. Under the
Traffic tab, I've tried configuring HTTP thinking it was a header issue.
However all METHODS, all EXTENSIONS, and all HEADERS are allowed.
Attachments that ARE WORKING through the firewall are...
.jpg
.doc
.bmp
.txt
I did send an attachment of a zone file (just a standard notepad document)
that was named virginia.com.zone that did NOT WORK. It failed with the same
error message as the .jpg attachment.
Any suggestions on what I should try next? I'm at a loss and it's now
costing me money as I'm loosing some good customers.
Thanks in advance for your time and consideration.
Paul
