I am trying to get copied packets from machine A to machine B. When I ping machine B from machine A, I get a ping response. When I ping machine A from machine B, I don't get a response. Machine A has 1 network interface. Machine B has two network interfaces with eth0 on a different subnet than machine A and eth1 on the same subnet as machine A.
Machine B (eth1) can ping 10.0.3.1 (gateway), but not 10.0.3.100 (machine A).
Both machines are running on AWS.
Here is machine B (ping not working):

I am trying to get a copy of all traffic from machine A (eth0) to machine B (eth1) while still having use of machine B (eth0) for accessing the internet (which works right now). I think this is a routing issue, but I can't find the problem and most searches seem to refer to firewall issues (see iptables), netmask (they match), and routing (I can't find the issue).
The mangle table seems to be incrementing count, so packets are being copied, but tcpdump shows there are no packets received by machine B (eth1). This is the end goal ^

I am trying to get a copy of all traffic from machine A (eth0) to machine B (eth1) while still having use of machine B (eth0) for accessing the internet (which works right now). I think this is a routing issue, but I can't find the problem and most searches seem to refer to firewall issues (see iptables), netmask (they match), and routing (I can't find the issue).
The mangle table seems to be incrementing count, so packets are being copied, but tcpdump shows there are no packets received by machine B (eth1). This is the end goal ^

I am trying to get copied packets from machine A to machine B. When I ping machine B from machine A, I get a ping response. When I ping machine A from machine B, I don't get a response. Machine A has 1 network interface. Machine B has two network interfaces with eth0 on a different subnet than machine A and eth1 on the same subnet as machine A.
Machine B (eth1) can ping 10.0.3.1 (gateway), but not 10.0.3.100 (machine A).
Both machines are running on AWS.
Here is machine B (ping not working):
