You will also have to setup a nat exempt statement to allow access.<br />

For the traffic traveling from Public to Private Ip ranges (When u ping from 153 range to 172.24 range), you will have to do a NAT .. and that too a Static NAT. Form a public network you cannot ping a Private IP.<br />

Hi, thanks for your comments. <br />
Can you please give me an example of a nat exempt rule that would allow the 153.87.180.0 network access to the 172.24.0.0 network?

Hi,<br />
Can someone please help me with this? I can’t seem to get my firewall rule to work.<br />
We have an existing network 153.87.180.0 and I want to allow a new subnet 172.24.0.0 to access servers on this network. I have added this rule (using Cisco SDM)<br />
<br />
permit source network 172.24.0.0 mask 0.0.255.255 protocol ip destination network 153.87.180.0 mask 0.0.0.255<br />
<br />
But I still can’t ping a computer on the 172.24.0.0 network from the 153.87.180.0 network? What have I missed?

Firewall rule to allow access to new subnet

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.
