Hello All,<br />
I'm working toward my CCNA security and I'm using GNS3 for labbing, everything seems to be working fine but for some reason the connection between my ASA and my local PC is very sporadic, it connects and disconnects on its own for no reason or that's what it seems like and its very frustrating, I've attached my topology.<br />
My Local network is on a 192.168.1.x subnet, the cloud in the topology is representing my local pc.<br />
I can ping 8.8.8.8 from the G/0 interface of the ASA and I can also ping the my local router at 192.168.1.1.<br />
My Local pc is 192.168.1.11 which is on the same subnet but it doesn't always work, my pc's IP/MAC is in the arp table of the ASA and everything matches, I have no firewall enabled on my pc and no AV. Any help would be appreciated..<br />

CCNA Security - Lab

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

A personal computer is a general-purpose computer whose size, capabilities and price make it useful for individuals, and is intended to be operated directly by an end-user with no intervening computer time-sharing models that allowed systems to be used by many people, usually at the same time. Personal computers may be connected to a local area network (LAN), either by a cable or a wireless connection, and through that to the Internet. A personal computer may be a laptop computer or a desktop computer running an operating system such as Windows, Linux or Macintosh OS.

Network security consists of the policies adopted to prevent and monitor authorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, and covers a variety of computer networks; conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access.

Network Security

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
