How to use DNS pool in NAT rule?

Varun Ganesan

Hi

 

I am running sophos UTM for firewall management tool. Application is hosted in AWS.

 

 

We have a requirement to NAT the internet traffic to AWS Network load balancer (NLB) and all traffic requires to use DNS names and not IP address.

 

Following is the traffic flow.

Internet Application - > Sophos UTM - > AWS NLB - > AWS EC2 instances (Application hosted).

 

I created a Network definition having following details 

Name - QMFT-NLB-Pool

Type - DNS Pool

Hostname- qmft-test-edge.domain.name (resolves to 3 IP) 

When configuring the NAT rule , I am not able to use this DNS pool in the Action after the rule is matched.

 

Can you please help me to setup DNS pool in the NAT rule.

 

 

Thanks

Varun

    Hi Varun and welcome to the UTM Community!

    As background for the following, see #3 through #5 in Rulz.

    As you may have guessed, this solution can't work for what you want to do.  If using the "QMFT-NLB-Pool" object in place of "External (Address)" doesn't accomplish your goal, please answer the following questions.

    Is the UTM in your location or is it in AWS?  What/where is "QuantasWiFi?"  Why would the clients in "QuantasWiFi" be going to your "External (Address)?"  What FTP client are they using?

    Cheers - Bob
