Wildcard domain in packet filter?

Is there a way to specify a wildcard when defining networks by domain name?

I am trying to setup a packet filter rule to block all traffic to/from all hosts in a particular domain.  I've tried using the "DNS group" option but it does not seem to accept wildcards.

For example, I want to block all traffic from *.baddomain.com

I've created a DNS group entry for "baddomain.com" (without the quotes), and it will resolve one IP address, but it does not appear to resolve any of the subdomains.  If I enter "*.baddomain.com" it says it's unresolved.

I'm only using packet filter rules; no proxies.

The contextual help does not specify, and I've had no luck searching the forums, so if this is answered elsewhere, I apologize!

We're running 7.502.

Thanks!

  • Hi, David, and welcome to the UTM Community!

    No, this is not possible at present and there hasn't been much "noise" about it being considered.
