After the popularization of broadband, Cisco wireless router settings are frequently faced. So today, I am going to introduce you to the configuration skills of Cisco Wireless routers. I hope this article will teach you more things and bring convenience to your life. After broadband popularization, many friends who have multiple computers or laptops want to install wireless hotspots at home. Because they se

Now that Cisco Nat is flexible, Can Linux implement it? The answer is yes! Linux netfilter is super flexible, and Linux Nat is not flexible because the iptables program is not flexible. xtables-Addons rawnat has taken an important step towards static Nat, iptables restricts the development of static Nat in Linux! So I put aside iptables, first implemented the kernel module based on Netfilter, and then used procfs as the user interface to see how to im

Cisco configuration instance _ Cisco dual-Egress NAT configuration objective: to simulate the routing function based on the original address policy when a dual-Egress link is available, and access to the external network from different original addresses is realized, in most cases, the vro uses NAT to translate the Intranet address on the external port, so this experiment also uses dual NAT to translate the

Tags: process proc ima RAC Technology share static term ADOBy configuring static routes, you can achieve an increase in routing entries for routers in a relatively simple network.However, if there are more than 20 routers in a network, it is difficult to configure static routes to accommodate the complexity of routing entries and changes in the network. At this point we can use the RIP protocol to configure simple dynamic routing, thus reducing the workload.Configuration ideas1 Configure the IP
