GRE Tunnel in Vyatta
::GRE Tunnelling::
==================
Tutorial ini menggunakan:
-vyatta 6.0 livecd
-virtualbox, bridged network mode
Topologi:
LAN WEST <==> WEST <==> cloud <==> EAST <==> LAN EAST
LAN WEST = 192.168.40.0/24
lo WEST = 10.10.1.1/32
WEST-cloud = 192.0.2.0/27
cloud-EAST = 192.0.2.32/27
lo EAST = 10.10.1.2/32
LAN EAST = 192.168.60.0/24
GRE Tunnel = 10.20.20.0/24 (WEST<=>EAST)

cloud dalam keadaan nyata merupakan jaringan WAN. namun Antum dapat menyederhanakannya dengan router yang menghubungkan antara WEST dan EAST dengan routing protocol. -Wallahu a’lam-
Untuk melihat bahwa koneksi tunnelling kita berhasil atau tidak, Antum dapat mengcapture paket data yang masuk/keluar interface. Disana akan terlihat apakah datang dari IP tunnel atau bukan.
