Enumeration
Enable or disable the TCP checksum check for local packets received on the corresponding interface. Disabling the check may improve performance for some local applications (i.e. remote CAPI). This object should only be set to dont-check on interfaces for LANs without further routers. Packets received from routers may have a corrupted TCP checksum and TCP will no longer be able to detect those packets. The TCP checksum must be checked by the receiving TCP under any circumstances, when TCP header compression is used on any router.
