# [ASP_SFW_ALG_LEVEL_ADJUSTED](https://apps.juniper.net/syslog-explorer/?msg=ASP_SFW_ALG_LEVEL_ADJUSTED)

## SYSLOG Details
- **Message**: ALG <variable>sfw-application-name</variable> specified by stateful firewall or CoS rule was reduced to <variable>nat-application-name</variable>, because twice NAT does not support ALG <variable>application</variable>
- **Help**: ALG was ignored in rule that also uses twice NAT
- **Description**: A twice Network Address Translation (NAT) rule is applied to the same source or destination addresses as a stateful firewall or class-of-service (CoS) rule that applies an application-level gateway (ALG) other than Internet Control Message Protocol (ICMP) or traceroute. The configuration is invalid, because only those ALGs are supported in combination with twice NAT. The ALG configured in the stateful firewall or CoS rule was ignored, and only the application configured in the twice-NAT rule was applied. The adaptive services software accomplished this internally by adjusting the indicated ALG value (which is not supported with twice NAT) to the indicated supported value.
- **Type**: Event: This message reports an event, not an error
- **Severity**: warning
- **Cause**: -
- **Action**: Change the configuration so that twice-NAT rules (defined at the [edit services nat] hierarchy level) are not applied to the same source or destination addresses as rules defined at the [edit services stateful-firewall] or [edit services cos] hierarchy level that include ALGs other than the supported ones.
- **Attributes**: sfw-application-name
nat-application-name
application
- **Facility**: LOG_PFE
