Hello everybody,

I have the following problem:
On a computer that has two ethernet interfaces (eth0 = DMZ Zone, eth1 = Internal Zone), i do not get an ipv6 address on eth0 if i enable masquerading on firewalld (firewall-cmd --add-masquerade --zone=dmz --permanent).

With disabled masquerade, i get assigned by the router an IPv6 address (2a02:8071:X:X::X).

In the man page is the following:
Enable IPv4 masquerade for zone. If zone is omitted, default zone will be used. If a timeout is supplied, masquerading will be active for the specified amount of time.  timeval is either a number (of seconds) or number followed by one of characters s (seconds), m (minutes), h (hours), for example 20m or 1h. Masquerading is useful if the machine is a router and machines connected over an interface in another zone should be able to use the first connection.

So if i activate masquerade should have no impact on ipv6.
