Anyone can do me favor? <br />
<br />
After I configure routing protocol at InsideRouter and OutsideRouter, Inside router can ping outside router through PIX. Here is topology: InsideRouter----PIX----Out<wbr />sideRouter<wbr /><br />
<br />
InsideRouter ip address 1.1.2.2 255.255.255.0<br />
OutsideRouter ip address 1.1.1.2 255.255.255.0<br />
PIX inside interface 1.1.2.1 255.255.255.0<br />
PIX outside interface 1.1.1.1 255.255.255.0<br />
<br />
After i added nat(inside) 1 1.1.2.0 255.255.255.0 and globe(outside) 1 1.1.1.3-1.1.1.10 at PIX, the InsideRouter cannot ping OutsideRouter<br />
<br />
After i remove nat(inside) 1 1.1.2.0 255.255.255.0, the InsideRouter can pint the OutsideRouter again<br />
<br />
Is there something wrong ?

Inside route cannot pint outside router throught PIX after adding nat

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

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

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.
