I have created a VPN between a remote site and our headoffice
The remote site has a Cisco 877 Router and the HeadOffice has a Cisco 3005 Concentrator.
The VPN i have created is up and running and I can connect to devices at either sides of the VPN.
The problem i am having is, i am planning on rolling out thinclients at the remote site that connects to a terminal server at the headoffice.
When i set up the thinclients, they connect but then disconnect straight away.
I think this is down to the default MTU size being too small but i don't know if i am correct, and also in what interface to change it on.
