This is certainly not the first article on "Quick Guide to building a VPN using Cisco devices, however, we still hope that this guide will become an all-in-one guide for users who use ASA 5505 devices to set up VPN and connect to the Internet. The ASA itself has a setup wizard, but this wizard does not cover all aspect

Cisco's ASA Firewall is a stateful firewall that maintains a connection table (conn) about user information, by default the ASA provides stateful connections to TCP and UDP traffic, and is non-stateful to the ICMP protocol.The message traversal process for Cisco ASA is as follows:A new TCP message view to establish the

Cisco ASA L2TP over IPSEC configuration details 1. Create a VPN address pool Ciscoasa (config) # ip local pool vpnpool 192.168.151.11-192.168.151.15 mask 255.255.255.0 2. Configure the Ipsec encryption algorithms 3DES and SHA. Ciscoasa (config) # crypto ipsec transform-set TRANS_ESP_3DES_SHA esp-3des (esp-sha-hmac) 3. Set the IPSec transmission mode to transport.

There are many VPN products on the Cisco ASA Web VPN configuration market and their technologies are different. For example, in the traditional IPSec VPN, SSL allows the company to achieve more remote users to access the VPN in different locations, this service enables more network resources to be accessed and has low requirements on client devices, reducing the

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 ma

Premise: With the development of the network, network security has become an important topic at present. More and more companies will choose to use the firewall as the company's egress device. Compared with the router, the firewall not only has the forwarding routing function, it can also filter internal and external traffic to further enhance the security of the company's network.
