Problem description:
When the SSG series firewalls of Juniper can access each other through VPN dial-in or direct mutual access between different network segments, sometimes PING can be reached, but the service cannot be accessed, such as WEB and shared files.
Problem Analysis:
These problems are often caused by the identification of data packet fragments by devices during data transmission.
Okay, everybody.This weekend seems to have been very fast, because there are too many customers after-sales problems need to actively cooperate with the processing, in short, the time for engineers to do a good job of technology has gone, many times we have to assume too many original role, and not just Huawei, China three, Cisco.this share, but also focused on the configuration of the idea of Huawei, rock Mesh firewall configuration ideas, in favor o

As noted in the previous entry, you can increase this with the Envar, but you need to use them in multiples of 8, and the combination of
SSG-5 is the Juniper Firewall entry level products, some emergency situations need to log into the intranet of a PC or server, need to temporarily open the firewall 3389 ports and do the corresponding VIP mapping.
The command line is naturally the fastest and least error-prone way. The setting method is as follows:

The problems that customers face
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

People who have used juniper products should know a little, juniper product password Forget the words is a very painful thing, why say so? Come down and listen to what I have to tell you!
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).
