>Description:
About at_ifawithnet() in /src/sys/netatalk/aarp.c, there is the following code.
if ((nr->nr_phase == 2)
    && (nr->nr_firstnet <= sat->sat_addr.s_net)
    && (nr->nr_lastnet >= sat->sat_addr.s_net))
	break;
"nr->nr_firstnet", "sat->sat_addr.s_net", "nr->nr_lastnet" and "sat->sat_addr.s_net" are the value of network-byte-order and 2 bytes. If it works in x86 architecture (little endian), there are cases we can't judge correctly.

In this part, we check the Network-number of destination(client) whether it is in the range that is orderd from seed router or not.
>How-To-Repeat:
One of the example as follows.
We set the range of Network-number from 0x0110 to 0x0200 at the seed router.
>Fix:
About at_ifawithnet() in /src/sys/netatalk/aarp.c, we must modify as follows.
if ((nr->nr_phase == 2)
    && (ntohs(nr->nr_firstnet) <= ntohs(sat->sat_addr.s_net))
    && (ntohs(nr->nr_lastnet) >= ntohs(sat->sat_addr.s_net)))
	break;

Original current Netatalk has been modified already.
