hello all,
Let me start of by thanking Tom for a great product. I have been using
Shorewall for a long time now.
I have a small issue that is complicating my IPv6 setup: when Linux is
configured as router it does not by accept router advertisements when
forwarding is enabled. That can be enabled on more recent kernels by
setting /proc/sys/net/ipv6/conf/$INTERFACE/accept_ra to 2.
Tom, would it be possible to add an option in the interfaces that sets
the interface. Adding an option accept_ra=x would allow setting it. This
would be quite similar to setting the forwarding there.
>From the kernel documentation:
accept_ra - INTEGER
Accept Router Advertisements; autoconfigure using them.
It also determines whether or not to transmit Router
Solicitations. If and only if the functional setting is to
accept Router Advertisements, Router Solicitations will be
transmitted.
Possible values are:
0 Do not accept Router Advertisements.
1 Accept Router Advertisements if forwarding is disabled.
2 Overrule forwarding behaviour. Accept Router Advertisements
even if forwarding is enabled.
Functional default: enabled if local forwarding is disabled
disabled if local forwarding is enabled.
Judging by the purpose of the variable it might be appropriate to add it
as an option. It is somewhat similar to the forwarding option....
Thanks in advance for your feedback
Kind regards, Louis
