Most firewalls will have access to &quot;ping&quot; returned packets turned off. &nbsp;This is to stop icmp attacks (consuming firewalls processing to force them to slow down and fail).<br />

If you would like to enable this on your Office firewall (PIX 501) I believe...you have to issue these commands.<br />
(config)#icmp permit any any (applied to an interface for all icmp)<br />
(config)#icmp permit any outside (this is all the traffic on the interface allowing icmp messages.)<br />
<br />
To restict only return packets when ping from home.<br />
(config)#access-list outside-&gt;in permit icmp any host xxxxxxxxxxxxxx echo-reply<br />
add this traffic to your access-list for traffic &nbsp;coming in...<br />
<br />
If you are using the Cisco client.....turn on the log and see what is happening. &nbsp;This can be verbose if you want....

Easy VPN question

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.

Networking Protocols

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

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.
