ip / country block does not work with waf

Hello,

Drop/Reject Firewall Rules doesn't work with WAF since v18 EAP 1, I've reported it back then but they never fixed It; In v17.5 It used to work as expected.

If you want to open a support case for It, you can use the NC-51857 as reference.

(Read LuCar Toni post below.)

Now you should create a DNAT Blackhole in order to do country filtering for WAF.

Thanks!

Isnt this known to be a restriction to the decoupling of NAT? 

If you create a NAT Rule for unwanted destination countries, it should hit. The WAF rule will pickup and overwrite the Deny rule.

The only answer I got from It has "No ETA for the fix".

Apparently yes, I've just tried It out and worked as expected, just feels really strange to have a NAT Rule doing this instead of a Firewall Rule.

Thanks again

can you show me your NAT rule?

Sure, here's the Rule:

Use the "Rule Position" at "Top".

• Original Source: Here you will select the Countries / Continent you want to block.
• Translated Source: Leave as "Original".
• Original Destination: Mine is at #Port2 since It's where the WAF is currently located.
• Translated Destination: Here you can create a Dummy IP (Blackhole IP), you can use any Local IPv4 that isn't being used.
• Original Service: HTTP and HTTPS, or If the WAF is located on another port - you can then create a new Service in there.

Thanks!

thank you, it works

that means i need 2 entries in the firewall. 1. drop rule firewall and nat rule to be sure?
