IP Alias + 1:1 NAT how to?

I just setup the KVM Appliance and i'm having trouble with setting up multiple public IP's and using 1:1 nat to forward those addresses to VM's behind the firewall. This is the first time i've used any sophos firewall software. What I've done so far is create an IP Alias under my WAN Interface (PortB:0). I then created a firewall policy with the non-http based policy template. Here is a screenshot of the created rule: http://i.imgur.com/35Wtl4h.png Unfortunately this does not work. I'm not really sure what to do now. I enabled icmp ping on the firewall for testing and i'm able to ping the firewall IP fine, but unable to ping the Alias IP.

Thanks for any help!

What is your gateway address of the "Alias IP"? Does it have your Sophos XG Firewall as gateway?

Hi bobdole, I have a similar problem. If you have not given up, you can try this console command:

arping -s ALIAS_IP -c 5 -I PortE1 GATEWAY_IP

and then check if it works.

Sophos Support found (in my situation) a problem with arp table.
