When you connect a VPN site with an external company, the IP address segment of the company that was originally used to connect with the other party is forced to become another address segment due to a change in the company's internal network, however, it is difficult for the other company to negotiate with each other. It is true that VPN cannot be used. In the previous versions of ASA, there is no way to do this. You can only add a vro inside the

I. Overview: I listened to the ASA course of yeslab's instructor QIN Ke and talked about ASA's random initialization of serial numbers to disrupt TCP. So I set up an environment for testing and found that not only is the serial number initialized by TCP disrupted, the subsequent TCP packet serial numbers will also be disrupted. ---- Postscript: After listening to the subsequent tutorials, we know that the initialization serial number is disrupted beca

TopologyRequirement: You can use the Cisco Firewall ASA to access servers in the Internet and DMZ through the Intranet. servers in DMZ can be published to the network for access by Internet users.I. Use of Cisco simulated FirewallBecause we do not have real devices, we use a virtual system using the Linux kernel to simulate Cisco's firewall. The simulated firewall can be downloaded by ourselves, we also need to use a software to connect to the simulat

Currently, my company uses all static IP addresses. There is an ASA5505 firewall in the company, in this firewall, some users must be restricted from using certain applications, such as QQ farms. To implement these functions, we need to bind ARP to the ASA 5505 firewall, and then use the access control lists to restrict these IP addresses and MAC addresses. The specific configuration is very simple. Let's take a look at how to configure ARP binding on

Step 1 of Cisco ASA firewall VPN configuration: Create an address pool. To remotely access the client, you need to assign an IP address during logon. Therefore, we also need to create a DHCP address pool for these clients. However, if you have a DHCP server, you can also use a DHCP server.

I. Overview: The acs4.x initial HTTP access Port is 2002, and subsequent ports are randomly changed by default from 1024~65535, It is not a problem to access the outside area from the inside area of ASA, but if you access inside from the outside area of the ASA, there is a problem and it is not possible to release all the acs4.x ports. Two. Basic ideas: A. Defining the range of changes in acs4.x dynamic

At present, the network used by my company is all static IP address, inside the company has a ASA5505 firewall, should lead the requirements, in the firewall to limit a part of users can not use certain applications (such as QQ farm, etc.), and the leader of the computer does not make any restrictions. To implement these features, we need to do an ARP binding above the ASA 5505 Firewall and then use the Access control list to restrict these IP address

I. Overview: In actual work, it is estimated that two ISP lines, such as China Telecom and China Netcom, are often connected using ASA, and there is not enough budget to buy load balancing equipment, however, we want to achieve load sharing and automatic switching of links. We want to return traffic from China Telecom, from China Telecom to China Telecom, and from China Netcom to China Telecom. When one of the lines fails, all traffic never goes throu
