>Environment:
System: NetBSD speedy 1.4.1 NetBSD 1.4.1 (SPEEDY) #1: Tue Dec 7 13:23:26 CET 1999 pantzer@speedy:/usr/src/sys/arch/alpha/compile/SPEEDY alpha


>Description:
	When doing installation by for example FTP, sysinst checks that the
	router given is reachable with ping. This is very often not the case
	when the router is a firewall with ICMP disabled, and it's _very_ 
	annoying when NetBSD is not installable due to this.
>How-To-Repeat:
	Turn off the ICMP echo reply functionality in the nearest gateway
	and try to install with sysinst :-)
>Fix:
	There are (at least) two ways to fix this:
	1) If ping fails, ask if it should continue anyway instead of 
	   just fail.
	2) Check if the gateway sends an arp reply (if install over ethernet).
	   If it does, then it's clear that the gateway is reachable.
