The EGRET excess of diffuse Galactic gamma rays shows all the featuresexpected from dark matter annihilation (DMA): a spectral shape given by thefragmentation of mono-energetic quarks, which is the same in all sky directionsand an intensity distribution of the excess expected from a standard darkmatter halo, predicted by the rotation curve. From the EGRET excess one canpredict the flux of antiprotons from DMA. However, how many antiprotons arriveat the detector strongly depends on the propagation model. The conventionalisotropic propagation models trap the antiprotons in the Galaxy leading to alocal antiproton flux far above the observed flux. According to Bergstrom et.al. this excludes the DMA interpretation of the EGRET excess. Here it is shownthat more realistic anisotropic propagation models, in which most antiprotonsescape by fast transport in the z-direction, are consistent with the B/C ratio,the antiproton flux and the EGRET excess from DMA.
