Here is the setup:
1. The network 220.127.116.11/23 is dynamically translated to 18.104.22.168 when accessing the resources 22.214.171.124 and 126.96.36.199 on port 443. This has been working for months, then last week it stopped working.
1. To resolve the problem on scenario A, host within the 188.8.131.52/23 network were statically translated to individual IP addresses. This is now working.
Another solution for scenario A is scenario C, the network 184.108.40.206/23 is translated to 220.127.116.11 upon reaching PIX, Identity NAT is applied and this setup is working.
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.
