[USG] display firewall session table verbose
15:11:25 2013/12/18
Current Total
Sessions: 40
http VPN: public --> public
Zone: trust --> untrust TTL: 00:10:00 Left: 00:08:59
Interface: GigabitEthernet0/0/1 NextHop: 58.251.159.1 MAC: 00-0f-e2-a2-a2-61
<-- packets: 144 bytes: 6340 --> packets: 74 bytes: 3951
192.168.100.28:1036 [58.251.159.112:2048] --> 111.206.79.100:80
Which of the following descriptions is incorrect:

A) The host on the internal network 192.168.100.28 establishes an http connection with the external network 111.206.79.100.
B) The NAT-translated address is 58.251.159.112.
C) The MAC address of the outgoing interface of the firewall is 00-0f-e2-a2-a2-61.
D) Firewall interface GigabitEthernet0/0/1 belongs to the untrust zone.

4. The WeChat voice (TCP) service of a site experienced a large delay, and the delay reached 3 seconds. As its egress NAT gateway, the firewall is configured with easy-ip nat mode (single egress), with link state detection disabled, TCP aging time of 30 seconds, small business traffic, and nearly 50,000 sessions to the voice server. Through the session, you can see a large number of packets of one-way access to the voice server.
What is the correct cause and solution for this failure?

A) The solution could increase the TCP aging time to 600 seconds.
B) If there is no inconsistency between the round-trip paths on the link, you can enable the link status detection function, and the aging time is default, which can solve this problem.
C) The aging time of the TCF session is too short, and it takes time for the firewall to create a new session.
D) After the firewall session is aging, the port after the NAT of the new connection is inconsistent with the port used to establish the connection with the server, resulting in no response from the server. The client needs to re-establish the connection after timeout before sending data.
