MOSS 2007 - TMG 2010 - InfoPath Forms

I have a friend with the following:

Public facing SharePoint site, accessed through TMG 2010.  We would like to put an InfoPath form on the site that allows anonymous submissions.  The vendor that is hosting the site/hardware is telling us it's not possible with TMG.

Anyone know the answer?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.


I would try doing the following:

I assume your internal URL for the form  is:

Am I Correct?

I would create a HTTPS publishing Rule where I would Publish The above website on a HTTPS Listener, And for the allowed path in the publish rule I would Enter*. The Listener would have to be configured to "Not require authentication and not allow clients to authenticate directly"

The External URL would look like this:


You could also make it prettier by mapping the Path*



Did the vendor specify a reason as to why this can't work?

You can also look a this, It might give you a hint:

Find the part "Configure the ISA Firewall with an PPTP VPN Server, SSL VPN Server and CDP Web Publishing Rule"

This is the issue we get when submitting a form from an anonymous user.  We were able to repeat the error in an environment without TMG:

"Form submission failed. (User: , Form Name: Test, IP: , Request: http://vm-park-outr/_layouts/Postback.FormServer.aspx, Form ID: urn:schemas-microsoft-com:office:infopath:Test:-myXSD-2010-08-20T17-43-26, Type: DataAdapterException, Exception Message: The form cannot be submitted to the following location: http://vm-park-outr/Test/2010-08-20T14_36_06.xml. There is a problem with the Web server. Make sure the Web server exists, try again later or contact the Web server administrator. Access denied.)"
So If I understand correctly, MOSS seems to be the problem, as it won't accept anonymous authentication?

yep.  seems to be a common problem out there.  no problem submitting anon to a list.  but to a doc or form library, seems to be difficult.
On the other hand, have you added a mapping for the external URL to the MOSS server ?
Justin SmithSr. System EngineerAuthor Commented:
nope, we've already set that.

Got the answer from Microsoft.......

No, InfoPath will not allow anonymous access to submit a form. This is by design and is a security issue.
