Hello,
I have a problem with a Cisco 826 router and nat.
Until now, we had the following network:
INTERNET
|
|
|
|
FLOWPOINT ROUTER : External IP 217.136.183.122
| Internal IP 192.9.100.1
|
|
|
|
|
|
MULTITECH ROUTER : External IP 192.9.100.2
| Internal IP 192.8.100.1
|
|
|
+--- Mail server IP 192.8.100.3
|
|
+--- Web/FTP server IP 192.8.100.19
|
|
|
INTERNAL NETWORK
This is working just fine.
We intend to replace the first router (FLOWPIONT wich we rent from our provider)
with the cisco 826.
Our provider has configured it for us and it seemes al just fine, but our servers
can't be reached from the internet anymore.
I guess the problem lies in the combination of the routers
Here is the configuration overview:
