Firewal - ASA 5515

[Manoel Goncalves]

Hi,

I am setting up a NAT firewall.

Could you help me understand why the below:

Asymmetric NAT rules matched for forward and reverse flows; Connection for udp src outside-AeC-EBT:10.230.127.35/55812 dst inside-AeC-EST:192.168.224.15/162 denied due to NAT reverse path failure

Think you

Most often this happens when a specific NAT is defined in one direction and an "any" NAT covers the return path.

If you can share your NAT configuration we can verify the problem. Otherwise check packet-tracer on the ASA for a more specific answer from the firewall directly
