 AsetofFirewallRulesthatallowTCPtraffictoports21and22.Becausetheserulesrequireyouto
specifyasingleIPaddressontheinsideofthefirewall,theIpScopeelementismodifiedtolimittherange
ofIPaddressesavailableonthevAppnetworktoasingleaddress.
AnyVmthatconnectstothevApp
networkdefinedinthisNetworkConfigSectionisgiventhisaddress.
 ANatServiceelementthatmapsaroutableexternalIPaddresstotheinternalIPaddressallocatedtothe
VmbythevAppnetwork.TheVAppScopedVmIdvalueinthiselementistakenfromthe
VAppScopedLocalIdelementoftheVmandtheVmNicIdvalueistakenfromits
PrimaryNetworkConnectionIndex.SeeExample 5‐12
onpage 75.
WheneveryoumodifyavAppnetwork,aswedointhisexample,youmustbesurethatthemodificationsare
consistentwiththenetworkconnectionrequirementsofthevirtualmachinesthatconnecttothenetwork.The
vAppinthisexamplecontainsasingleVm.AsshowninExample 5‐12
onpage 75,thatvirtualmachine’s
NetworkConnectionelementspecifiesanIPaddressthatwillnotbeavailableafterthevAppnetworkhas
beenreconfiguredasshowninExample 5‐11.Example 5‐14onpage 77correctsthisproblem.While
Example 5‐11usestheIpScopeelementtorestricttheIPaddressesavailableon
avAppnetwork,itisusually
morepracticaltokeeptherangeofaddressesavailableonavAppnetworksomewhatwider,andapplyany
firewall‐relatedIPaddressrestrictionsbymodifyingtheNetworkConnection oftheVmtowhichthe
FirewallRulesapply,aswedoinExample 5‐14.Awiderrangeof
IPaddresseswouldallowthisvApptobe
modifiedtoincludeadditionalvirtualmachines,andtheIPaddressrestrictionappliedinExample 5‐14would
allowtheFirewallRulesinExample 5‐14toremainvalid.
