Will IPS inspect decrypted traffic on a gateway with site-to-site VPN?

I am trying to figure out IPS workflow on an R80.10 gateway with site-to-site VPN. Does it inspect the traffic after it is decrypted or just the encrypted traffic which probably won't have much to be inspected. Thanks.

On an R77.30 gateway traffic decrypted from a VPN will only be inspected if the Protection Scope setting is set to "Perform IPS inspection on all traffic", assuming the VPN tunnel is terminating on an external interface.

For an R80.10+ gateway, IPS will inspect the traffic after decryption assuming a TP rule matches the decrypted traffic attributes, and the Profile in the matching TP rule's Action column calls for IPS inspection.
