Hey everyone, I've got a bizarre issue here. We have a MT pppoe-server that seems to work fine for everyone except a customer with a cisco 1700 router connecting as a pppoe-client. We have set our max mru and mtu in our pppoe server to 1400. However, when the cisco connects the MT box shows its MTU=1400 and MRU=1500. They have a lot of problems sending data. My guess is that there MRU should be 1400. So far I have not found any way of getting them there. Cisco documentation is no help and they only have a setting for MTU. Any suggestions would really be appreciated. It seems like someone else in the world must have successfully gotten a Cisco router to connect to a MT pppoe-server. Thanks again!
