6. Proxy ARP requires that TCP/IP packets flow between two network interfaces (the virtual
and real/physical interface). This requires that “IP datagram forwarding” be enabled. Enter
the command CHGTCPA (Change TCP/IP Attributes), and change the value of IP datagram
forwarding to *YES as seen in Figure 13-25.
Figure 13-25 Change TCP/IP attributes
Note: After you enable datagram forwarding, ping the address of the i5/OS TCP/IP
interface on the virtual LAN. If the interface responds, then the set up of Proxy ARP is
complete and is ready for use by the Linux partitions.
