A router is refusing to forward IP packets, and snoop reveals that packets are arriving on its interfaces, but it is refusing to forward packets and route them. What command verifies that the router is currently configured (in the kernel) to forward IP packets?
ndd -get /dev/udp ip-forward
ndd -get /dev/ip ip_forwarding
ndd -get ip-forwarding /dev/tcp
ndd -set /dev/ip ip_forwarding 1
ndd -set /dev/ip ip_forwarding 0
