Hello,
I've recently updated to the 28th of August snapshot and I've discovered that I
cannot add static routes with an indirect next-hop, for example where the
gateway
address is not directly connected on an interface but is known via another
static
route.
I believe that this was introduced by the changes in sys/net/route.c at
revision 1.316
after which rt_setgwroute can return ELOOP.
I was previously running the 13th of August snapshot and in that version I
didn't
have any problems related to this.
Here is a simple example. If there is any other information that I can provide
please
let me know.
