Step 4—Configuring TCP/IP attributes
To configure the TCP/IP attributes, type option 3 on the Configure TCP/IP menu. The Change TCP/IP Attributes (CHGTCPA) display is shown (Figure 8).

Type choices, press Enter. |

TCP receive buffer size . . . . | 8192 | |
TCP send buffer size | 8192 | |
UDP checksum | *YES | *SAME, *YES, *NO |
IP datagram forwarding | *YES | *SAME, *YES, *NO |
IP source routing | *YES | *SAME, *YES, *NO |
IP reassembly | 10 | |

For information about the various parameters for this command, see the online help. In this step only the IP Datagram Forwarding (IPDTGFWD) parameter is discussed.
IP Datagram Forwarding
Specifies whether your system should forward datagrams destined for other networks. The default value is *NO.
Step
Note: If you are not using X.25, then proceed to “Step
If you use an X.25 connection to reach TCP/IP hosts with a public or private packet switched data network (PSDN), you need to add remote system information for each remote TCP/IP host. You must define the X.25 network address of each system if you use a switched virtual circuit (SVC). If a permanent virtual circuit (PVC) is set up by the network connecting your system with your remote TCP/IP partner, you need to know the local logical channel identifier of this PVC.
Adding Remote System Information (X.25)
To add an X.25 remote system address, type option 5 on the Configure TCP/IP menu. The Work with the TCP/IP Remote System Information display appears, as shown in Figure 9 on page 17.
