This problem was supposedly fixed with MR2 Fix ID 1197749. After installing RU5, the cisco client does not work giving an error saying there is firewall policy mismatch. Deinstalling RU5 immediately fixes the problem. Apparently the file fwsvpn.dll which was supposedly removed is now back. Manual removal of the file does not work as SEP detects the file is missing and reinstalls it.
I have tried this with all recent versions of Cisco VPN client.
