Here is the setup:
Scenario A
1. The network 1.1.1.0/23 is dynamically translated to 5.5.5.5 when accessing the resources 7.7.7.7 and 8.8.8.8 on port 443. This has been working for months, then last week it stopped working.
Scenario B
1. To resolve the problem on scenario A, host within the 1.1.1.0/23 network were statically translated to individual IP addresses. This is now working.
Scenario C
Another solution for scenario A is scenario C, the network 1.1.1.0/23 is translated to 5.5.5.5 upon reaching PIX, Identity NAT is applied and this setup is working.
Questions:
What caused the dynamic NAT to stopped working?
How can we restore dynamic NAT from working again?
Isolation shows that Static and Identity NAT are working.
NOTE: IP addresses here are not the actual IP Addresses in production.
