2 When the FWSM receives the frame on the inside interface, the MAC address of the client is added to the MAC address table; it then forwards the ARP request on the outside interface. 3 The host on the outside replies to the ARP request. 2). 5 The host now begins the Telnet session by sending a SYN packet to the host on TCP port 23. 6 Because this is the ﬁrst packet of a connection, the FWSM performs ACL check, AAA, and so on (refer to Chapter 2 for details) to validate that the packet is allowed through.
If you are considering a PIX today, a better solution would be the next-generation appliance, the ASA. ASA In addition to the capabilities of the PIX, the ASA also has the capacity of supporting the Advanced Inspection and Prevention Security Services Module (AIP-SSM). This is an inline Intrusion Protection System (IPS) used to detect and drop malicious trafﬁc. The Content Security and Control Security Services Module (CSC-SSM) is the other module supported in the ASA. It provides antivirus, antispyware, antispam, antiphishing, and ﬁle and URL blocking, as well as URL and content ﬁltering.
This process allows the ﬁrewall to dig into the data portion of the packet and match on protocol compliance, scan for viruses, and so on and still operate very quickly. Reusing IP Addresses A feature that is common among all ﬁrewalls is Network Address Translation (NAT) and Port Address Translation (PAT) . NAT obfuscates the IP address scheme you are using internally, and the PAT function helps minimize the use of public address space. Figure 1-5 shows how a ﬁrewall can be used to provide NAT and/or PAT functionality.
