[K12OSN] OT - Linux router - I'm stuck <-long

[Tim Litwiller]

Ok, I'm trying again.   I had to make their network operational so had 
to remove the routers.
But now I have the 4 computers on my bench that I have re setup
and it sure seems to be a config problem since it has almost the exact 
same problem as the first time.
only this time the RHS router isn't letting the others ping the internet 
gateway either.

DO = District Office
RMS = MiddleSchool
RHS = HighSchool
PE = Elementary

DO
eth0 = 172.16.96.1
eth1 = 10.0.0.2 and connects to RMS's eth2

RMS
eth0 = 10.0.1.2 and connects to RHS's eth1
eth1 = 172.16.32.1 and connects to switch in RMS building
eth2 = 10.0.0.102  and connects to DO's eth1

RHS
eth0 = 172.16.1.1 and connects to switch in RHS Building and then to 
internet gateway at 172.168.1.254
eth1 = 10.0.1.102 and connects to RMS's eth0
eth2 = 10.0.2.2 and connects to PE's eth0

PE
eth0 = 10.0.2.102 and connects to RHS's eth2
eth1 = 172.16.64.1 and connects to switch in PE building

PE router can ping each router but not internet gateway
RHS router can ping each router and internet gateway
RMS router can ping each router but not internet gateway
DO router can ping RMS router but not the rest of the network.
