Block ip dan port camfrog messenger

Block ip dan port camfrog, Akhir-akhir ini populernya camfrog ,sebuah alternatif messenger yang berbasis text dan video memiliki efek yang kurang bagus bagi trafic data di jaringan internet. Padatnya trafic karena banyaknya cliet yang menggunakan messenger video ini akan sangat terasa apabila bandwidth kita pas-pasan, dan sebagian dari admin networking (termasuk teman saya) akhirnya memutuskan untuk memblock paket data dari software camfrog ini. Dibawah ini dapat di lihat log dari aktivitas software client camfrog messenger tersebut :
