# Firewall Builder 5.3.0 Release Notes

SourceForge: Tickets

## Summary

In addition to bug fixes and minor enhancements, v 5.3 includes the following new features:

- Support for Junos Access lists
- Show all release notes

### Support for Junos Access lists

Firewall Builder now supports generating output for the Junos platform. This implementation is based on the Cisco IOS code and shares codebase where applicable.

#### Units and interfaces

The Junos compiler expects the units to be subinterfaces of the main interfaces. E.g. unit 10 is a subinterface of ge-0/0/0.
To configure ge-0/0/0 unit 10, do the following steps:

1. Add a new interface and rename to ge-0/0/0
2. Add a new interface and rename to unit 10
3. Make interface unit 10 a subinterface of ge-0/0/0

#### Deny and Reject

In the policy viewer, the Deny action will generate the following output

    then { discard; }

while the Reject action will generate

    then { reject; }

You may set parameters for the Reject action to specify ICMP reply.

### Show release notes for previous releases

You may now select any of the available release notes in the release notes viewer, not only for the current version.

## GUI Updates

- When using Dummy and deleting an object in the object tree viewer, any objects using only that object will now use Dummy instead of Any.

## Changes in support for NXOS

- Added support for compiling a single rule for NXOS.

## Other changes

- Fixed compile error: QApplication::setGraphicsSystem is removed in Qt5.

- Fixed NULL pointer dereference for Dummy interface when right clicking on the Dummy interface in the object tree viewer.
