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 func-
      tions 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).
