Is IPSec not available on AC87U anymore or have I misunderstood something?
It never was available for that model.
Hmm, true. I cannot find that info in the changelog now so I must have been confused. Or could it be available in standard Asus firmware?
It never was available for that model.
It requires kernel changes that are incompatible with pre-compiled modules from third parties.
No. Until Asus adds it (which is highly unlikely at this stage), it's not possible.
