Real juniper devices are expensive, so we use simulators to simulate juniper routers and juniper srx firewalls. The topology is simple:

The Juniper SRX Series firewall is based on the Juniper Jnos system. Initial login username is root and password respectively null.
Change your password first after entering. The order is as follows:

Today, we will demonstrate how the Juniper SRX Firewall runs ipsec vpn + OSPF with Cisco routers.

To configure the firewall HA, follow these steps:1. First, directly connect the HA control signal ports of the two firewalls. The HA control signal port is the port specified by the manufacturer.Device Model:For SRX100 devices, connect the fe-0/0/7 port to the Fe-1/0/7 portFor SRX210 devices, connect the fe-0/0/7 port to the Fe-2/0/7 portFor SRX240 devices, connect the ge-0/0/1 port to the ge-5/0/1 portFor SRX650 devices, connect the ge-0/0/1 port to

Organizations cannot tolerate attacks in the network spreading to all sensitive resources of the company. Businesses want to be able to quickly identify, control, and eliminate attacks to ensure that network resources are not compromised or compromised. To further refine perimeter firewalls and protect the internal network from increasingly complex types of attacks, including attacks that hide in network traffic or attacks that completely bypass security precauti

The problems that customers face
As the network expands and security threats grow and become more complex, traditional heterogeneous firewalls can pose a risk to the network. The security solutions offered by many vendors can pose multiple challenges for the enterprise: the need to use multiple management interfaces at the same time, information that requires up-to-date attack threats, or different patches to deploy on different devices. This will not only cause the enterprise to spend a lot of
Oh! Finally went to work in the company. I used to learn Cisco's routing exchange, but our company asked to use the Juniper Firewall, no way I had to self-study! But fortunately, the company has provided two juniper firewalls. So let's take a look at our Juniper firewall. Ho

The loss of the password is unrecoverable, so we have to regain administrative privileges by restoring the factory default settings (the original configured parameters, certificates, etc. will be deleted).

Today just learn to juniper firewall in the user authentication, so today we take a look at the Juniper Firewall user authentication.

2, Auth User: Authenticated Users
