This line puts all traffic from 192.168.77.0/24 into NAT pool 0 (NAT
You probably want to adjust your ACL inside_nat0_outbound to add "any
object-group DM_INLINE_TCP_3" (i.e. make it the same as outside_cryptomap).

This line means all other traffic will be NATted, so as long as your
inside_nat0_outbound doesn't exclude it, you'll be OK.
