Abstract
Methods are directed towards initializing a path maximum transmission unit value for two gateways in communication via a network tunnel (e.g., VPN environment). The initialized path maximum transmission unit value is used in establishing the network tunnel of the two gateways. Methods are also directed towards synchronizing path maximum transmission unit values for the two gateways after the network tunnel has been established. These methods minimize the occurrence of dropped data packets arising from mismatched path maximum transmission unit value between the gateways.
