How to tell which Node is hosting a EIP in a Cluster on AWS

ZP.

Hi there

 

This is probably a really stupid question, but 

 

1) In a H/A Deployment of UTM on AWS, how do I tell which node is hosting the EIP from inside the WebUI of the UTM, and if there are multiple EIPs how do I tell this also? And can I tell this from AWS Console also if both Nodes already have their own Extertnal IPs showing from the Instance Manager inside of AWS EC2

 

Thanks

    To move EIP from one Node , to another : 

    aws ec2 associate-address --instance-id i-xxxxxxxxx --allocation-id eipalloc-xxxxxxxx

     

    Use the AWS CLI

     

    Another question

     

    I am trying to bind multiple EIPs to a single interface..

     

    I can add multiple private IPs with no issue, eg eth0  10.0.0.5 , 10.0.0.6, howver I can only add one EIP to each interface it seems. In this case, 10.0.0.5 having a EIP no problem, but if I try add a EIP to 10.0.0.6, which is on teh same interface, it just removes the exisitng EIP, and replaces with the new EIP I am trying to add.

     

    Is anyone aware of how to get around this?

     

    Also, you can see from the AWS console, which node is hosting an EIP , so if it is in a cluster, click on your running Sophos UTM instance, and it will show you what EIP it is hosting.

     

    Hope that helps / hope someone can help me 

     

    Thanks
