    nat issue with inside and dmz interfaces on asa firewall…

    Locked

    by techrepublic ·

    Hello experts, I have a NAT issue which is bugging me. Got a 3 armed ASA with inside, outside and dmz interfaces. trying to get communication between a computer on the inside (192.168.101.22) and a computer in the DMZ(98.23.65.130). Tracing packets i get the messages below:

    ————————————

    %PIX|ASA-3-305005: No translation group found for protocol src interface_name:dest_address/dest_port dst interface_name:source_address/source_port
    A packet does not match any of the outbound nat command rules.

    This message indicates a configuration error. If dynamic NAT is desired for the source host, ensure that the nat command matches the source IP address. If static NAT is desired for the source host, ensure that the local IP address of the static command matches. If no NAT is desired for the source host, check the ACL bound to the NAT 0 ACL.

    ————————————

    Here’s the relevant config – external IP’s have been modified to protect the innocent.

    Any idea how to fix this? I’m a newbie when it comes to troubleshooting NAT. Any help is greatly appreciated. Thanks all.
