In a lab environment, I have three systems. One has two network cards
(I'll call it the gateway system), while the other two only have a
single card. I have subnetted a class C address and have one system on
each side of the gateway system. Each of these uses the gateway system
as the "default" route. I also have IP forwarding configuring on the
gateway system.
>From the gateway system, I can ping either of the two other systems.
>From each of the two systems, I can ping either interface on the
gateway. However, I can't ping from one system, through the gateway, to
the other system.
I was concerned that there may be a routing problem. So, I configured
tcpdump on one system and tried to ping it from the other system. It
appears that the gateway is not forwarding the ping requests, since no
pings are traversing through the gateway to the other network.
Can anyone provide additional advice?
BTW, I just loaded Linux 5.0 on the gateway system and have not made any
modifications to the standard kernel.
