I've connected my pc directly to my dlink 300t modem and determined that the best mtu would be 1400, using tcp optimiser.
My normal setup is an ipcop installation creates a ppoe connection to adsl modem on the red interface. Adsl modem is in bridge mode.
Now where must I change the mtu settings?
I've changed the ppp0 mtu setting with ifconfig on the ipcop box to reflect a mtu of 1400. Shown as follows
Now what about the eth0 and eth1 interfaces on the ipcop box, they are currently set to 1500?
Also what about all the clients on the network, must they be changed from the default 1500. Can this be done with the interface-mtu option setting in the dhcp server?
And lastly the modem itself is a busybox and has a whole bunch of interfaces with the mtu's all defaulted to 1500, it has a br0, br1, eth0 and nas0.
