Scanning router port to router security, Catalyst 2960S Price network management is usually the default port router(80) to change it, so the first step we crack the router password is must find the router wEBport management.

If the router UPnP (universal plug and play, is a general term for a group of protocol) functionis turned on (usually the router by default UPnP is turned on), then the router will open a L900 port.

We use TP Link router as an example, as long as the open http://192.168.1.1:l900/igd.xml router view the http://192.168.1.1:80808080 is the router wEB login port.

If the UPnP is management closed the case, then we can only scan tool to scan. Open the Xscan, enter the IP address 192.168.1.1

The configuration of the Cisco Voip

The basic principle of VoIP is: the speech air-ap1262n-e-k9 data codes are compressed by voice compress algorithm, then the voice data according to TCP/IP standards for packaging, through IP network packets sent to the receiving, and then string these voice packets, after decompression treatment, restorethe original speech signal, thus achieve from the Internet to send voiceobjective.
The experimental environment: Cisco 3600 Router, 12.3 IOS.
The configuration of the Cisco Voip:
