Only the CAC 10.30.70.0/24 subnet has a NAT rule.

If you are initiating traffic from a host on that subnet, it should work.

Hi

you won't have internet from either TC or CAC.

In your config, you've a missconfiguration:

object network inside-tc
nat (CAC,outside) dynamic interface

To mae it working, you'll need to remove the nat above and do the config below:

object network inside-cac
nat (CAC,outside) dynamic interface

object network inside-tc
nat (TC,outside) dynamic interface

Thanks

let me know if that works

The NAT command is

The NAT command is misconfigured with wrong real interface in your configuration. The object inside-tc is having the subnet which is directly connected behind TC interface. So NAT statement should have TC as the real interface, not the CAC interface. Correct NAT statement should be following

Object network inside-tc

Nat (TC,outside) dynamic interface
