in a RUT240 with FW RUT2_R_00.07.01.4, I have created the firewall rule attached in the image.
I would like that this OUTPUT rule matches only the traffic on WAN interfaces. Instead in iptables I see the following rule:
root@RUT240_0000:~# iptables -nvL OUTPUT
Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
0 0 ACCEPT tcp -- * * 0.0.0.0/0 0.0.0.0/0 tcp dpt:8000 /* !fw3: TEST_OUPUT */
As you can see in the "out" field is set to "*" and not to the specific WAN interfaces.
Could someone explain this behavior?
