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

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

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

  -fvalue
      Sets ipforwarding and ipgateway to one (like the -s option), 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 option cannot be combined with the -r option. Only application
      gateways for firewall services use this option.

  -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 options.







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.
