Using same enc domain for remote access on more than one firewall

[the_rock]

Hey guys,

Just for my own sanity, though we already confirmed with the customer doing this caused the issue, but they were wondering if doing so, one can make it work? So essentially have SAME remote access enc domain for 2 clusters, one for on prem and one Azure?

I cant really see how that would work, but just wondering if its even possible? if not, could they use same random subnets from large group already used for onprem to test Azure side or in order to use same one, it would need to be done during cutover window?

Tx as always!
