iprsetup(8)
NAME
  iprsetup - Internet Protocol router setup

SYNOPSIS
  /usr/sbin/iprsetup -s
  /usr/sbin/iprsetup -sd
  /usr/sbin/iprsetup -r
  /usr/sbin/iprsetup -rd
  /usr/sbin/iprsetup -fvalue
  /usr/sbin/iprsetup -fvalued
  /usr/sbin/iprsetup -d

FLAGS
  -s	    Sets ipforwarding and ipgateway to one, which means the system
	    functions as an IP router.	This flag cannot be combined with the
	    -r flag.

  -r	    Resets ipforwarding and ipgateway to zero, which means the system
	    does not function as an IP router. This flag cannot be combined
	    with the -s and -f flags.

  -fvalue   Sets ipforwarding and ipgateway to one (like the -s flag), and
	    also sets ipfirewall to one, which means the system functions as
	    an IP firewall.  Additionally, sets ipsrcroute and ipchkredirects
	    according to the specified value.  The following table shows the
	    valid values and their meaning:


	    _________________________________________________________
	    Value   Meaning
	    _________________________________________________________
	    0	    Sets both ipsrcroute and ipchkredirects to zero
	    1	    Sets ipsrcroute to zero and ipchkredirects to one
	    2	    Sets ipsrcroute to one and ipchkredirects to zero
	    3	    Sets both ipsrcroute and ipchkredirects to one
	    _________________________________________________________

	    This flag cannot be combined with the -r flag.

  -d	    Displays the values of ipforwarding and ipgateway.	The values
	    are displayed after the values are changed when combined with the
	    -s, -r, and -f flags.

DESCRIPTION
  The iprsetup command sets the ipgateway and ipforwarding variables in the
  running kernel allowing your system to function as an Internet Protocol
  router.


  When ipfirewall variable is set to one, the following variables are also
  set:

  ipsrcroute
	    Indicates whether IP source-routed packets are accepted (1) or
	    dropped immediately (0).

  ipchkredirects
	    Indicates whether ICMP Redirect messages are authenticated (1) or
	    accepted with no authentication (0).

  The iprsetup command is automatically executed by netsetup when you
  configure your network daemons.  It is also executed by the
  /sbin/init.d/inet script when you reboot your system or restart the network
  on your system.

FILES
  /usr/sbin/netsetup
	    Contains the /usr/sbin/iprsetup command.
