4 In that case it sounds like linux has bridged them across from the other
5 interface. Does this find anything?
6 tcpdump -i enp2s0 net 192.168.1.0/24
7
8 If it doesn't maybe generate some layer2 broadcast traffic on enp1s0 to see
9 if you can see that traffic in the tcpdump on enp2s0. Something like;
10 echo 0 > /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts
11 ping 192.168.1.255
12
13 After the test is done turn it back on with;
14 echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts
15
16 I've never bridged with linux. Bridging is usually a bad option - if you
17 can I suggest you move to a routed and/or NATed solution. Clean and simple
18 is best.
