Rules / NAT, client block

Hi,

you do not need a Nat rule for drop.

do you hav3 any other rules with any as the local network?
when you review logviewer with a refined search using one IP address which rule does it show as the address is using?

your drop rule will also need to be at the top of your rule list,

Hi,

yes, the rule is the first rule in the list so that the first traffic will select this rule and block the client.

Ok, I'll take a look at it with the LogViewer.

When do I use a link to Linked NAT?

The rule will only block the client if there is no other source LAN, network ANY, type of rule. Linked NAT, when you have multiple gateways, you want to use a hsirpin rule otherwise a general (default) NAT (MASQ) rule will be okay.

Debugging linked NAT is pain from my point of view.

Linked NAT Rule is simply a relic from a older version, which was rather popular in other products. Beside that, i would not go down this road to create linked Nat rules. You can do this, but you can simply stay with the default NAT for MASQ and DNAT for internal. This should cover 90% of the use cases of NAT. The Rest can be done separately. There are no real use cases for Linked NAT.

They came from the migration of V17.5 to V18, as we decouple Firewall from NAT. 

ok, thanks.

ok, thanks.
