XOT settings
The Advanced Network XOT Settings are as follows:
Default source IP address interface x,y
The values in these two text boxes specify the interface ( None , PPP , ETH ) and instance number
of that interface that IP address that XOT sockets should use instead of the interface that the
socket was created on.
Note Even when this parameter is not configured, the router uses the IP address from the
interface on which the socket was created. It uses the source address specified in this
parameter only if it will cause the traffic to match an Eroute and therefore be sent using
IPsec or GRE.
NB of XOT listening sockets
The maximum number of XOT sockets available. Use this setting to reduce the number of XOT
sockets in order to free up more general-purpose sockets for other purposes. The default value
of 0 enables the maximum number of XOT sockets available.
Maximum ACK time for XOT data
The maximum time allowance for a remote unit to acknowledge TCP data transmitted by a
unit’s socket. If this timer expires, the socket is aborted. The default value of 0 disables the timer.
Note There is no requirement for the remote unit to acknowledge received data immediately,
therefore setting this parameter to too small a value is not recommended. Some stacks
delay sending TCP ACKs in order that they can be incorporated with data sent by the
application.
Do not deactivate outgoing XOT sockets when interface disconnects
When enabled, this setting sets outgoing XOT sockets not to close when the interface they are
using disconnects.
