The site with the Adtran router has a checkpoint firewall behind the router. The problem I have is the Exchange on the Adtran site keeps disconnecting from the exchage server located on the other side of the Netscreen. I have tried setting the MTU size from 1500 to 1400 and also 1300 on the client behind the checkpoint device. I am seeing alot of fragmentation and reassembly of packets in the checkpoint. Does anyone have any ideas?
