The IPSec VPN realizes the network expansion, the firewall realizes the control and the filtering to the network traffic, therefore has the influence to the IPSec VPN communication. The default ASA maintains a state session only for UDP/TCP traffic, and therefore discards the ESP traffic that is returned. There are two ways to solve the problem One uses ACLs to release ESP traffic. Two applications check

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

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. QUANMA-T (config) # ip local pool vpnpool 192.168.10.100-192.168.10.199 mask 255.255.255.0 Step 2: Create IKE Phase 1.

If only one segment is restricted, enter 60, and set the length to 4, in this way, 99 numbers can be used. routepattern represents the type, and our 3 represents siptrunk.16.

Explanation of CentOS7 firewall commands The firewall in CentOS 7 is a very powerful function, but it has been upgraded in the firewall in CentOS 7. Let's take a look at the usage of the firewall in CentOS 7 in detail. FirewallD provides dynamic

The basic function of a firewall is done by six commands. In general, unless there is a special security requirement, this six command can basically handle the configuration of the firewall. The following author on the combination of Cisco firewall, to talk about the Basic Firewall
