Tunnelingallowstheuseofapublicnetworktoconveydataonbehalfoftworemoteprivatenetworks.Itis
alsoawaytotransformdataframestoallowthemtopassnetworkswithincompatibleaddressspacesoreven
incompatibleprotocols.
GenericRoutingEncapsulation(GRE)isatunnelingmechanismthatusesIPasthetrans

ortprotocolandcan
beusedforcarryingmanydifferentpassengerprotocols.Thetunnelsbehaveasvirtualpoint‐to‐pointlinks
thathavetwoendpointsidentifiedbythetunnelsourceandtunneldestinationaddressesateachendpoint.
ConfiguringaGREtunnelinvolvescreatingatunnelinterface,whichisalogicalinterface,thenconfi
g
uringthe
tunnelendpointsforthetunnelinterface.
TosetupGREtunnels:
1. FromTunnels,selectGRETunnels.TheTunnels:GRETunnelspaneopens.
2. FromtheTunnels:GRETunnelspane,clickAddTunnel.
Aseriesofwizardpanelshelpsyouconfiguretheconnection.
3. IntheTu

elNamefield,enteranameforthenewtunnel.
4. Inthedescriptionarea,typeadescriptionthathelpsyoufurtheridentifythetunnel.ClickNext.
5. Inthenextwizardpane:
 IntheRemoteWANIPfield,typetheIPaddressofthegatewaytowhichyouwanttoconnect.
 (Optional)FromtheSavedNetworkdrop‐downlist,selectthenetworkthatistoberoutedthrough
