Affected VPNsec (and RU VPN) users

The new RU Fortigate firewall, that is in place since December 13, manages fragmented IP packets inconsistently. Depending on the VPN client and its settings, this can cause problems for VPN users. The ISC found a solution for the cenral RU VPN in changing the configuration of the RU VPN as of 2016-12-19 15:50 hours. While waiting for the final solution, a temporary workaround has been used in the Fortigate firewall on April 19, which makes the problem disappear.
