Configuring network interfaces
Auto indicates that the router will accept whatever the remote suggests. For the other values,
the remote must accept and request the key size specified, else the PPP negotiations will fail.
Enable MPPE stateless mode
When this setting is enabled, the router negotiates stateless mode in which the session key is
changed after the transmission of each packet. Stateless mode may be useful for lossy links.
Note MPPE does not provide authentication, only encryption. This is because the encryption
keys are determined by the PPP engines themselves on start-up.
Use PPP m for processing CHAP
TCP transmit buffer size n bytes
When the value in this text box is set to a non-zero value, the router uses the value to set the
size of the TCP buffer for transmitted packets. This is useful for slow and/or lossy connections
such as satellite links. Setting this buffer to a low value will prevent the amount of
unacknowledged data from getting too high. If retransmits are required, a smaller transmit
buffer helps prevent retransmits flooding the connection.
