 	    Recommended option for single homed hosts and stub network
 	    routers. Could cause troubles for complicated (not loop free)
 	    networks running a slow unreliable protocol (sort of RIP),
 	    or using static routes.

 	0 - No source validation. 
 
-	NOTE: do not disable this option! All BSD derived routing software
-	(sort of gated, routed etc. etc.) is confused by such packets,
-	even if they are valid. When enabled it also prevents ip spoofing
-	in some limited fashion.
-
-	NOTE: this option is turned on per default only when ip_forwarding
-	is on. For non-forwarding hosts it doesn't make much sense and 
-	makes some legal multihoming configurations impossible.
+	Default value is 0. Note that some distribution enable it
+	in startip scripts.
