To create a site-to-site tunneled connection, you can install a MCSE Certification as a gateway on each of two networks. A demand-dial connection is then configured between the two VPN servers. 4g LTE router See Also For more information about site-to-site VPNs, see the “Lesson 3: Designing Demand-Dial Routing Between Private Networks” topic later in this chapter. Redundancy is provided by establishing multiple VPN servers. If one VPN server fails, client sessions are disconnected. However, clients can connect again by using a different VPN server. 4g LTE router To reduce the necessity to configure multiple connectoids one for each VPN server, use Network Load Balancing. However, don’t confuse redundancy with load balancing. Load balancing can be provided via round-robin Domain Name System DNS or clustering. Network load balancing, 4g LTE routera Microsoft clustering technology that spreads requests for a single IP address among several Microsoft Windows servers, can also provide load balancing in addition to scalability and redundancy. 4g LTE router If a VPN server fails, client sessions will also fail and the user will be prompted to log on again. The user’s new session will be managed by one of the other VPN servers free Cisco practice exam questions n the cluster. 4g LTE router Figure 7-7 shows Microsoft network load balancing.

As was mentioned in tip number 1 we have ports open on our computer that can possibly allow a hacker in. Windows firewall which comes free with windows can block these types of ports. You can also purchase a third party firewall program that will help block these ports. There are many third party companies that provide excellent firewall programs. Firewall Gold.

As companies began using the Internet to sort, filter and gather data, it became apparent that there was a need to develop IP Internet Protocol addresses that would work within the confines of a private network. Usually, a router the computer device that transmits data packets between networks takes the data from the Internet and sends it over to a computer. However, utilizing the Network Address Translation NAT, the router is able to detect the packets emanating from the Internet and relay them to the proper element in the network.
