Following the previous "Juniper Old Driver Experience" (SRX Firewall optimization), Juniper old driver experience (SRX firewall NAT and strategy) The second video course was recorded on the line.1, two courses are completely independent and combined,SRX Firewall Optimization
Juniper Old driver Experience (SRX Firewall optimization) Video course on lineEveryone in the QQ group, the forum often ask questions, many people on the SRX double machine is not very understanding, the actual work encountered too many problems, provoked a little trouble.For this I recorded a Juniper old driver experi
Real juniper devices are expensive, so we use simulators to simulate juniper routers and juniper srx firewalls. The topology is simple:
Juniper router em0.0 ------------ VM1----------------SRX ge0/0/0.0
That is to say, the first
Today, we will demonstrate how the Juniper SRX Firewall runs ipsec vpn + OSPF with Cisco routers.

R1 simulates a cisco device, which is equivalent to a branch site. R2 simulates a carrier device, C1 is a zhuyun device, and bridging with
Processing process:
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:

The juniper device is different from other vendors, and adopts the configuration concept of submitting for effectiveness. This greatly reduces misoperations. Note: Al

Here we use the Stone check_traffic.sh plug-in, www.111cn.net the plugin's Project home page is: https://github.com/cloved/check_traffic, Because there was a special article about the plug-in log article ———— Nagios SNMP traffic monitoring check_traffic.sh, so this is not done in detail, only listed configuration can be.
