Correct that localhost (127.0.0.1) should only be talking amongst itself, but I was a bit concerned that the "home" zone might stop something it oughtn't to within that. -- uname -rsvp Linux 3.10.0-1160.119.1.el7.x86_64 #1 SMP Tue Jun 4 14:43:51 UTC 2024 x86_64 (yes, this is the output from uname for this PC when I posted) Boilerplate: All unexpected mail to my mailbox is automatically deleted. I will only get to see the messages that are posted to the mailing list. =============== Indeed only local traffic should travers over the loopback interface, however, I noticed some time ago, that it is not just 127.0.0.0/8 Even if you address an ip-address of one of your own Ethernet devices, the kernel manages to redirect it to the LO device.
