I have created a working VPN between a remote PC with Cisco VPN Client and Easy VPN server on Cisco 1802 (DSL). The Router has an dynamic external IP and is accessible over DynDNS. The problem is not the VPN connetion, but the communication between the remote PC and LAN behind the router.
Ping functions to all devices on the LAN
telnet 25 functions
Access to shares is taking ages, functions then sometimes, usually runs it into a Timeout
HTTP is taking ages and breaks then
Remotedesktop to a 2k server breaks
Remotedesktop to a 2k3 server opens the server window, but before the login mask breaks
