New Features Chapter 1 Introduction to the Firewall Services Module New Features Table 1-1 lists the new features for FWSM Release 4.1(1). Table 1-1 New Features for FWSM Version 4.1(1) Feature Description Platform Features Separate Host names for Primary and Secondary blades This feature lets you configure a separate hostname on the primary and secondary FWSMs. If the secondary hostname is not configured, the primary and secondary hostnames are the same. The following command was modified: hostname primary_hostname [secondary secondary_hostname]. Firewall Features Creation of UDP sessions with unresolved ARP in the accelerated path If you configure the FWSM to create the session in the accelerated path even though the ARP lookup fails, then it will drop all further packets to the destination IP address until the ARP lookup succeeds. Without this feature, each subsequent UDP packet goes through the session management path before being dropped by the accelerated path, causing potential overload of the session management path. The following command was introduced: sysopt connection udp create-arp-unresolved-conn. DCERPC Enhancement: In this release, DCERPC Inspection was enhanced to support inspection of Remote Create Instance RemoteCreationInstance RPC messages. message support No commands were modified. NAT/PAT Global Pool This feature lets you track and manage the usage of global pools for NAT/PAT configurations. usage enhancement The following command was introduced: show global usage. Reset Connection marked for Deletion You can now disable the sending of a reset (RST) packet for a connection marked for deletion. Starting in this release, reset packets are not sent by default. You can restore the previous behavior, so that when the FWSM receives a SYN packet on the same 5-tuple (source IP and port, destination IP and port, protocol) which was marked for deletion, it will send a reset packet. The following command was introduced: service reset connection marked-for-deletion. PPTP-GRE Timeout You can now set the timeout for GRE connectionss that are built as a result of PPTP inspection. The following command was modified: timeout pptp-gre.
