1
00:00:00.100 --> 00:00:06.600
The middle router translates traffic between the inside and outside networks.

2
00:00:20.650 --> 00:00:27.150
The outside router has no route back to the private source.

3
00:00:43.000 --> 00:00:50.000
Mark the inside and outside interfaces and add two static address mappings.

4
00:01:06.200 --> 00:01:15.200
Start a packet capture on the outside link, then send a ping from each inside source.

5
00:01:22.650 --> 00:01:30.650
Check the translated source in each request and the translated destination in the replies.

6
00:01:50.650 --> 00:01:58.150
Remove the first static mapping, clear active translations, and check both flows again.

7
00:02:05.900 --> 00:02:11.050
Save the configuration and reload the translating router.

8
00:02:25.300 --> 00:02:32.800
Check that the remaining mapping and its traffic still work after the reload.
