Hi, i am setting up a waas poc at a customer site. they use a linux box Zimbra as their email-server and owa as the email client. the problem is when they try to attach a file to their e-mail, they get the following error ???ztaglib.TAG_upload_failed???. When the wae is not on the network though, they are able to add attachment to their mail.Does any one have any idea what can be causing the problem?

1.the interception method being used is wccp.

2.services 61 intercepts traffic on the lan at the head office and 62 on the gre tunnel to the branch.

3.the waas version used is 4.0.9.b.10. The head office uses a 7206 vxr.

4.the devices are in the alldevicegroup.

5. no file services were configured.

6. the default policy was left unchanged.the portmapper settings were changed.

7. the problem is that its does not allow attachment to email and it does not allow files to be uploaded from the branch to the head office.

8. the config guide for wccp was followed

The adapter was already disabled. I have resolved the problem. someone set the branch router's interface connected to the wae to half duplex. Stumbled upon it when going through their switches config.

Kind Regards.
