Re: Can't access 1 IP address on Lan

hi ya curtis

do my silly question is.. where is the machine called 10.0.1.1 
that does not reply to pings ??
	- if you know where 10.0.1.1 is... do the same set of commands
	again ( route -nv, ifconfig -v, ipchains -L, etc

	- the 10.0.1.1 machine should be able to ping itself
	and should be ble to ping the local LAN and outside world

i am not 100% sure... but you might wanna turn off "null ipchains" rules
or at least have it pass all up  .. 

am assuming this is NOT the firewall and if it is... you're missing
all of  the  fw rules
