Connectivity Question>

I have client that is using a Mdeical Olan software suite.  The company uses an IP address starting with 172....  The practice recently changed ISP's.  The IPS gave me info with IP at 68.....  I spoke with proprietary software tech that indicated it I changed the Gateway and DNS address it work.  Well that is not the case, will not work.  This is just one thought I have:
If I install a router coming from Internet modem and use the ISP's static info and set the router as DHCP with the 172...addresses, will this work?

Or othr ideas and solutions!

ycguy1117,

What you have suggested will work.

On the Lan configuration, leave the 172 range and set up dhcp here.

On the external configuration, make sure Nat is enabled, and use the details from your isp .

try to see if you can automatically get your DNS/IP details from your isp first, im assuming you are using DSL?

1. *If* you still have the same internet connection hardware, nothing needs to change on your Internal side of the network; the *172. addresses should not change. The address that you need to check is the external side of the internet connection hardware, thats where the 68. address should be.

2. Check that you do not have a DNS problem by pinging googles ip address from a LAN Client.
(Windows) Start menu --> run --> cmd --> ping 66.249.89.99
