I have my main Astaro with Internet 1 working fine

I have a trial Astaro with Internet 2 working fine

After a few days testing Internet 2 I'm ready to merge it into my main Astaro and setup link balancing.

I configure an additional interface in my main Astaro and plug in Internet 2...

However I can't ping it. I can ping Internet 1 fine (I have check the appropriate boxes under ICMP to allow ping). I plug Internet 2 back into my trial Astaro and can ping it fine.

Why is Internet 2 not available on my main Astaro? I feel like I should be able to ping it externally before I proceed any further, yes?

Like I said, I simply dropped another NIC in, configured it with the assigned IP for Internet 2 ISP and that's all I've done. It seems like that's all I would need to do to get this far at least.

EDIT: Nothing appears in the Packet Filter Log - I searched on the IP of Internet 2 and the IP of the external machine I'm pinging from....
