Odd IPv6 Behavior?
by Linux_Kidd from LinuxQuestions.org on (#6E4JZ)
Well, this may not be odd, but I need more info.
I have a box that is an "appliance" with underlying Linux OS.
Here's the setup.
IPv6 and IPv4 is enabled, and httpd conf only has one Listen directive for tcp-443, but it's a IPv6 directive. lsof shows only the IPv6:443 for httpd.
I have a vuln scanner across the network (routing) that's using only IPv4, and it finds TLS1.1 (port tcp-443) on my appliance.
So, is IPv6 processing the IPv4 packet? I read some about IPv4 mapping and the "ipv6-only" setting for IPv6 stack, but I am not 100% on how all that works.
