Socket Settings
Default source IP address interface x,y
The values in these two text boxes define the interface (None,PPP,ETH) and the instance
number of the interface to use as a source address for IP when not using the interface that
the socket was created on.
The router creates general-purpose sockets automatically when the controlling application
requests them. As, for example, when TPAD calls are made over IP or XOT. Normally, the
source address used by the socket will be that of the outgoing interface (usually PPP).
However, for some applications such as when setting up a VPN, it may be necessary to
specify that the socket uses a different source address such as that of the local Ethernet
port. This parameter is used to specify the interface from which the source address should
be derived.
Note:
Even when this parameter is not configured, the IP address from the interface on which the
socket was created will be used. The source address specified in this parameter will only be
used if it will cause the traffic to match an Eroute and therefore be sent using IPsec or GRE.
Connect Timeout s seconds
The value in this text box is used to specify the amount of time after which a TCP socket
may remain idle before being closed. If the value is set to 0 the socket may remain open
indefinitely.
TCP socket inactivity timer s seconds
The value in this text box specifies the maximum period of inactivity (in seconds) that may
occur before and open TCP/IP socket is closed. The default value is 300 seconds (five
minutes) and should not normally require altering.
TCP socket keep-alive s seconds
The value in this text box specifies the amount of time (in seconds) between sending “keep-
alive” messages over open TCP connections. The purpose of these messages is to prevent a
connection from closing even when no data is being transmitted or received. The default
value of this parameter is zero which disables keep-alive messages.
