  calling an endpoint wich is connected to a gatekeeper behind a router !!

  Ok - maybe I should send my ini files to make 
  thinks clear:

  [Gatekeeper::Main]
Fourtytwo=42
Name=GKFI
TimeToLive=300
  ;first is the external ip of the gateway , second 
  the internal network !! i tried several 
  constalations
NetworkInterfaces=217.82.33.254,10.2.0.0/24 
  ; home doesent take any effekt to this problem 

Home=10.2.0.20

  [RasSrv::Neighbors]
  ; the neighbour GK wich is direct installed at 
  the router (external and internal ip )
  GK2=externalIP:1719;*;gk2pass

  [RasSrv::LRQFeatures]
; timeout value to wait 
  reply in 
  seconds
NeighborTimeout=4
;ForwardHopCount=2
;IncludeDestinationInfoInLCF=0
; 
  if your neighbor is a Cisco gatekeeper, you may turn on this 
  option
;CiscoGKCompatible=1

  [RoutedMode]
GKRouted=1
H245Routed=1
CallSignalPort=1720
;CallSignalHandlerNumber=2
;RemoveH245AddressOnTunneling=1
;DropCallsByReleaseComplete=1
SupportNATedEndpoints=1
Q931PortRange=50031-50040
H245PortRange=50021-50030
AcceptUnregisteredCalls=1
CallUnregisteredEndpoints=1

[Proxy]
Enable=1
InternalNetwork=10.2.0.0/16
T120PortRange=50011-50020
RTPPortRange=50000-50010
;ProxyForNAT=1
;ProxyForSameNAT=1

  [Gatekeeper::Auth]
; authenticate the LRQs by NeighborPasswordAuth 
  module
NeighborPasswordAuth=required

  [Endpoint]
Password=gkfi123

  [GkStatus::Auth]
rule=allow

  The other ini file is not important, because the other mashine is a 
  normal GKNat system in a box. It works fine with a third gk as its neighbour. 

  So pleaaase help !! 

  cheers

    hi folks , 

    I have got problems reaching an netmeeting 
    endpoint wich is connected to a gatekeeper behind a firewall: 

    [NM1]------>[GK]---------[NAT Router with 
    Ext IP] ------ internet ------[GK] ------ [NM2]

    If I call from NM2 to NM1 I Netmeeting says NM1 
    didnt answer the call. If I try the other way the Netmeeting says , not 
    connected. 

    At the Router I set static forward rules for 
    T120,RTPQ931,H245 and 1719 to the Gatekeeper. I also tryied some settings 
    with supportnatedclients and I set both Networks with 
    the Flag 
    NetworkInterfaces=extIP,intIp/subnetmask

    Anyone for an Idea what to do ???
