Hello,
I have a freebsd 11 box running as my network gateway and I’m having some
trouble trying to route ipv6 packets through an interface with only linklocal
address.
In short, what I’m doing is:
My freebsd gateway has one global scope address on lo0 interface, each other
interface has only a link local address fe80::1. Static routes for the global
scope subnets have been created, Each route was created using the command:
# route -6 add -net <net address>/64 -interface <dev>
The clients on each subnet have a global scope address and fe80::1 as default
gateway.
What is happening with this approach is that my gateway can’t reach the clients
on the subnets. Ping tests from the gateway to the client return the error
"ping6: sendmsg: No buffer space available”. On the other hand, when I try to
do a ping from client to gateway, the packets from the client are received by
the gateway but no response is sent. In my tests using a linux gateway with the
same approach, everything worked fine .
Is there something wrong with my setup? How can I get that approach working
using freebsd ?
Thanks in advanced,
Anderson
