We studied a magnetic turbulence axisymmetric around the unperturbed magnetic field for cases having different ratios l||/l⊥. We find, in addition to the fact that a higher fluctuation level δB/B0 makes the system more stochastic, that by increasing the ratio l||/l⊥ at fixed δB/B0, the stochasticity increases. It appears that the different transport regimes can be organized in terms of the Kubo number R=(δB/B0)(l||/l⊥). The simulation results are compared with the two analytical limits, that is the percolative limit and the quasilinear limit. When R<<1 weak chaos, closed magnetic surfaces, and anomalous transport regimes are found. When R~1 the diffusion regime is Gaussian, and the quasilinear scaling of the diffusion coefficient D⊥~(δB/B0)2 is recovered. Finally, for R>>1 the percolation scaling of the diffusion coefficient D⊥~(δB/B0)0.7 is obtained.
