I'm having a NAT issue with a ASA 5505 that I set up. The inside interface is 172.17.0.0/16 and I have a few devices on the inside. The outside interface is connecting to our office LAN on 172.16.0.0/16.
On the 172.17.0.0/16 network I can reach outside fine. From the 172.16.0.0/16 network when I trying connect in, I receive this error on the firewall:
Asymmetric NAT rules matched for forward and reverse flows; Connection for icmp src outside:172.16.13.179 dst inside:172.17.10.10 (type 8, code 0) denied due to NAT reverse path failure
This is what I have for a NAT:
Result of the command: "sh run nat"
nat (inside) 10 0.0.0.0 0.0.0.0
I know its a NAT issue, I'm just not sure what I need to do or add to allow the traffic inbound. It would be nice if I had a brief explanation to exactly what is happening also and why the added statement fixes the issue.
