VPDN (PPTP) ON CISCO 1841

i am configuring my Cisco 1841 following this guide:

http://www.cisco.com/en/US/tech/tk827/tk369/technologies_configuration_example09186a00801e51e2.shtml

The ruoter opens the tunnel and my clients see LOCAL IP ROUTER. All my LAN components  can't see
anything.

Is it a NAT Problem or Routing Problem ?

Re: VPDN (PPTP) ON CISCO 1841

The virtual-template interface references a pool called 'test'.


interface Virtual-Template2
ip unnumbered FastEthernet0/1
peer default ip address pool test
no keepalive
ppp authentication chap ms-chap pap


ip local pool test 192.168.126.227


Based on your NAT rules it looks as if this host may belong to your LAN subnet.  Is your LAN subnet 192.168.126.0/24?  If this is the case your LAN hosts will attempt to ARP for your PPTP host instead of routing the traffic to your router.  You should create an ip local pool that is unique from your LAN so that LAN hosts will route traffic to the router that will in turn send it to the PPTP host.  For example use 192.168.254.0/24 for the PPTP hosts.
