Unable to edit NAT-Firewall rule

It is by design. To be able to change the NAT rule for a firewall rule, you need to:

• Unlink the NAT rule from the NAT tab
• Link a new NAT rule from the NAT tab to an existing firewall rule

Feedbacks:

Please:

• Allow to edit and link the NAT rule from the Firewall rule
• From the Firewall rule, use the white space by providing information about the NAT rule you are linking to the rule. For example, NAT_NAME where a "i" information icon is availble and we can see the NAT rule proprierties without moving back and forth from NAT Tab.

You do not need to link a NAT rule to a FW rule. NAT rules operate on the matching criteria. NAT Rule linking was a needed step for migration. You do not need to unlink rules if you want to keep the same kind of setup you had previously. We would suggest however that over time you unlink rules and create NAT rules based on matching criteria. It may look complicated at first but it is actually more powerful and elegant.

If you have 100 FW rules now, and they are all MASQ rules that will mean 100 Linked NAT rules are created on migration. However it is very likely you could reduce this to a single SNAT rule which applies to all 100 FW rules by the matching criteria.

I  do not agree on this. Admins should be able to change the NAT from the Firewall rule also and not only from NAT tab. Also, from the Firewall rule, there should be a way to view information about the linked NAT rule. A name is not enough!

Thanks

I am working with V18 since couple of weeks and i do not use any Linked NAT Rules anymore. 

Would recommend to work with NAT Rules, which uses the Interface Criteria (for example WAN outbound).

You can actually use a default NAT Rule on the bottom with Matching Interface WAN and SNAT enabled (MASQ). So you would reduce the need of a Linked NAT Rule from X Rules to 1.

Do you read what I am complaining?

Please read carefully! Suggested answer is very bad.

I am just trying to point to a direction, which could lead to a much simpler rule set. 

If you want to work with Linked NAT Rule, then i would confirm this issue. 

But if you want to migrate to a one rule set setup, this would the way to go.

This would also solve your other issue.

That would be the Rule, which i am suggest. 

Here the documentation talks clearly:

Linked NAT rules

These are source NAT rules and are listed in the NAT rule table. You can identify them by the firewall rule ID and name.

XG Firewall applies firewall rules before it applies source NAT rules. If a NAT rule above the linked rule meets the matching criteria, XG Firewall applies that rule and doesn’t look further for the linked rule. However, linked NAT rules apply only to traffic that matches the firewall rule they are linked to.

You can unlink a linked NAT rule from the NAT rule table. Once you unlink the rule from the original firewall rule, you can edit the NAT rule. It will now be evaluated independent of the original firewall rule based on its criteria and not the original firewall rule criteria.

Guys, make sure when you develop or change a feature, to involve System Admin. I worked in environment with 4000+ users and imagine that you have to manage 400+ rules. Click-saving is the way to save admins time and life!

Even for a 4000 User Deployment, i would rather have a MASQ Ruleset, which simply pick up all traffic going to WAN and MASQ than to have 400 Linked NAT Rules.

On one of my appliances, there were 60 Linked NAT rules. I simply selected them all, deleted them and recreate one SNAT rule.

After that change, i was ready to go with the SNAT Traffic.
