Chapter 21 Logs Table 95 TCP Reset Logs (continued) LOG MESSAGE DESCRIPTION Exceed MAX incomplete, sent TCP RST The router sent a TCP reset packet when the number of incomplete connections (TCP and UDP) exceeded the user-configured threshold. (Incomplete count is for all TCP and UDP connections through the firewall.)Note: When the number of incomplete connections (TCP + UDP) > "Maximum Incomplete High", the router sends TCP RST packets for TCP connections and destroys TOS (firewall dynamic sessions) until incomplete connections < "Maximum Incomplete Low". Access block, sent TCP RST The router sends a TCP RST packet and generates this log if you turn on the firewall TCP reset mechanism (via CI command: "sys firewall tcprst"). Table 96 Packet Filter Logs LOG MESSAGE [ TCP | UDP | ICMP | IGMP | Generic ] packet filter matched (set: %d, rule: %d) DESCRIPTION Attempted access matched a configured filter rule (denoted by its set and rule number) and was blocked or forwarded according to the rule. For type and code details, see Table 105 on page 312. Table 97 ICMP Logs LOG MESSAGE Firewall default policy: ICMP , , Firewall rule [NOT] match: ICMP , , , Triangle route packet forwarded: ICMP Packet without a NAT table entry blocked: ICMP Unsupported/out-of-order ICMP: ICMP Router reply ICMP packet: ICMP DESCRIPTION ICMP access matched the default policy and was blocked or forwarded according to the user's setting. ICMP access matched (or didn't match) a firewall rule (denoted by its number) and was blocked or forwarded according to the rule. The firewall allowed a triangle route session to pass through. The router blocked a packet that didn't have a corresponding NAT table entry. The firewall does not support this kind of ICMP packets or the ICMP packets are out of order. The router sent an ICMP reply packet to the sender. P-660HW-Tx v3 Series User's Guide 309
