Hi,

I'm not experiencing a communication issue but I'm not sure I understand how 
"traceroute" works.

I don't know if the shorewall dump I'm attaching can be of any use but here 
goes.

A host in the "ibs" zone with IP addr. 10.215.237.228 performs a traceroute to 
a host in the "lan" zone with IP addr. 10.215.145.231.
The trace is as follows:
1 10.215.237.1
2 172.20.1.7
3 172.20.30.1
4 10.128.4.252
5 172.20.11.62
6 10.215.145.231

The trace and pings work just fine.

However, the IP addr. at pos 5 is assigned to the NIC facing the "caib" zone on 
the shorewall firewall. I would be expecting to see "172.28.17.105" instead of 
"172.20.11.62".

NIC enp2s0f1 IP addr. is 172.28.17.105 ("ibs" zone)
NIC enp2s0f0 IP addr. is 172.20.11.62  ("caib" zone)

If I sniff with tcpdump on both NICs while "ibs" host performs pings then I see 
traffic to/from NIC enp2s0f1, as expected. Nothing on NIC enp2s0f0.

So, if all's working fine then why isn't the "ibs" host seeing something like 
this instead?:

1 10.215.237.1
2 172.20.1.7
3 172.20.30.1
4 10.128.4.252
5 172.28.17.105
6 10.215.145.231

Thanks in advance,

Vieri
