Hello,
in our company we have a Cisco 1802 installed and need to use NAT.
During a configuration change for one of our customers we needed to change the inside and outside NAT interfaces.
The configuration worked fine until we have to make a change for our new video communication device.
Here are some snippets of the router configuration:
interface fast 0 (connected to the internet)
ip address 51.52.53.54 255.255.255.248
ip nat inside (we can't change this, because it's needed for another config)
interface vlan1 (local network)
ip adress 172.16.0.254 255.255.255.0
ip nat outside
The video communication device has the address 172.16.0.250 and should be externaly avaible via 51.52.53.55 so i did the following:
ip nat outside source static 172.16.0.250 51.52.53.55
The default gateway of the VCD is 172.16.0.254
After setting the NAT entry 51.52.53.55 becomes ping-able from the outside but the device isn't reachable by a web browser or another VCD.
Does someone has any ideas?
with kind regards

Hi Jacob,
If you do:
ip nat outside source static 172.16.0.250 51.52.53.55
ip nat inside source static 172.16.0.250 51.52.53.55

Hello,
thanks for your reply but i solved the problem meanwhile.
i replaced the current entry with this one
ip nat outside source static 172.16.0.250 51.52.53.55 add-route
and it worked for me.
greetings
Jacob
