Re: Assigned IP failed? Try increasing the MTU Tunnel size on the SecureClient machine's network adapter. If you are running the client on a Windows Platform, then it can be changed in your Network Connections, TCPIP Properties tab. No guarantees, but this resolved a very similiar issue I have experienced with previous versions of the SecureClient. HKeyLocalMachine\System\CurrentControlSet\Services \Tcpip\Parameters\Interfaces\Adapter Number ---> Change Value Data: 0xffffffff for Value Name: MTU |
