I have a VPN server connected to a DSL line. I connec to it from many sources. I feel that the performance is not always as good as it should be. Some functions are very quick, others are slow.
I have read that there may be a MTU issue. I am wondering if there is a way to monitor the MTU and see if packets are being fragmented. Is there some sort of packet monitor? What is the best way to troubleshoot this problems?
