NAT
NAT changes the addressing of packets. A NAT rule tells
the EdgeRouter what action to take with a specific packet.
Define the following:
• Criteria for matching packets
• Action to take with matching packets
Rules are organized into a set and applied in the specified
Rule Order. If the packets match a rule’s criteria, then its
action is performed. If not, then the next rule is applied.
Source NAT Rules
Source NAT changes the source address of packets;
a typical scenario is that a private source needs to
communicate with a public destination. A Source NAT Rule
goes from the private network to the public network and
is applied after routing.
Add Source NAT Rule To create a new rule, click Add
Source NAT Rule. Go to “Add or Configure a Source NAT
Rule” on page 25.

- Before making changes the administrator saved a backup configuration file with a working ipsec tunnel configuration 48
- Enter save and press the key 48
- Here is an example that uses the commit revisions command 48
- Lite user guide 48
- Manage the configuration file 48
- Note this is a backup if the edgerouter were rebooted it would still boot from the default file config config boot 2 after the administrator deleted the ipsec configuration and was configuring of the openvpn tunnel circumstances changed so that the ipsec tunnel was required again consequently the administrator reverted the edgerouter to its previous configuration with the ipsec tunnel 48
- On the remote tftp server a copy with the hostname and date is saved for each commit 48
- Scenario in the midst of the administrator changing an ipsec tunnel into an openvpn tunnel the administrator had to revert the edgerouter to its previous configuration with the ipsec tunnel 48
- To automatically make a remote backup after every commit use the commit archive configuration option enter location and press the key 48
- Typically you use the save command to save the active configuration to disk config config boot however you can also save the active configuration to a different file or remote server 48
- Ubiquiti networks inc 48
- You can also keep a specified number of revisions of the configuration file on the local disk use the commit revisions configuration option 48
- After viewing the history of system commits you decide to discard the last four commits by admin_5 roll back the system configuration file to commit 4 49
- After you verify that the changes should be saved use the confirm command 49
- Appendix a command line interface edgeroute 49
- For details on the commit revisions option go to manage the configuration file on page 45 49
- Lite user guide 49
- Note the following commands require that the configuration option commit revisions be set first 49
- Now you will see the comment when you use the show system commit command 49
- To add a comment to the commit use the comment command 49
- To display the changes in revision 0 use the show system commit diff command 49
- To display the entire configuration file for revision 0 use the show system commit file command 49
- To roll back to an earlier commit use the show system commit and rollback commands 49
- Ubiquiti networks inc 49
- When you work on a remote router certain changes such as a firewall or nat rule can cut off access to the remote router so you then have to visit the remote router and reboot it to avoid such issues when you make risky changes use the commit confirm command first then use the confirm command to save your changes 49
- You can also specify the number of minutes to wait but you must remember to also use the confirm command otherwise if you forget then you can be surprised by the edgerouter s reboot to its previous configuration 49
