SSL-VPN Cache clean

[#1]

Hey folks. Have an issue with SSL-VPN on a Fortigate 50B. Everything is working normally, we can access the web gui and bookmarks work, etc. However, the instant we enable the " cache clean" setting for the user group, the web browser hangs when we attempt to logout of the SSLVPN (must kill the process to close the browser). This occurs with IE7, not Firefox, on multiple workstations. I have verified that logout functions normally without " enable cache clean" turned on. Any ideas? I' ve checked the knowledge base and these forums without any success. Thanks in advance!

Let me know if you have any more specifics. Anyone else have any other ideas?

Anyone else have any other ideas?

I cannot reproduce the same error with Firefox 2.0.0.5 and MR5 patch1 in 100A for example. Maybe related with the size of ' Temporary Internet Files ' folder? I' ll re-try cleaning that folder before. Just an idea.

Could be, doesn' t mention " cache clean" specifically. ftp://support.fortinet.com/FortiGate/v3.00/MR5/MR5_Patch_1_GA/FortiOS-v3.00-MR5-Release-Notes-Patch-Release-1.pdf 2.6 VPN Description: The SSL-VPN daemon may crash under certain scenarios when a tunnel is brough up.

I can' t reproduce it in Firefox either, only in IE7 (Haven' t been able to try with IE6). Sorry if I wasn' t clear about that.

Load MR5 Patch 1 and see if the problem still exists. Unload all the SSL VPN plugins from IE, after you upgrade the FortiGate firmware you will be prompted to install new SSLVPN ActiveX plugins in IE.
