Severity: 3-Major


The NAS-IP-Address has the address of the local device sent with the bytes in reverse order (e.g.,, where is expected).


The server may be configured to check the NAS-IP-Address before allowing logins, in which case it would fail.


-- This affects IPv4 addresses only. -- BIG-IP system is configured for RADIUS authentication.


There is no workaround at this time.
