To prevent network interruptions caused by the failure of the Juniper firewall device and ensure uninterrupted operation of user services, we will describe the rapid recovery of the Juniper firewall under the fault.One of the backup configurations of the Juniper firewall and the restart of the device: if the system reset is required when the Juniper

When conducting a passive connection, the client uses the PASV command to tell the server to wait for the client to establish a data connection, and the server to respond, to tell the client what port on the server should be used for data transmission (randomly opened ). This kind of Working Mechanism brings about a serious problem: Passing IP addresses and port numbers in FTP commands (port or PASV) or answering them seriously conflicted with the ne

: nf_ip_pre_routing, Nf_ip_post_routing, and Nf_ip_local_out. The nf_ip_pre_routing implements the address translation of the source address that needs to forward the datagram, while the Nf_ip_post_routing addresses the destination address of the datagram that needs to be forwarded. The conversion of the destination address for the local datagram is implemented by Nf_ip_local_out. Datagram Processing: The mangle table is registered in the nf_ip_pre_routing and nf_ip_local_out hooks. Using th

Before the pix OS 5.0 (the version number of the pix operating system), you can only access the pix from hosts on the internal network through telnet. In pix OS 5.0 and later versions, you can enable telnet-to-pix access on all interfaces. When you need to telnet from an external interface to the pix Firewall, the telnet data stream must be protected by ipsec. That is to say, you must configure the
