VPDN clients unable to contact LAN servers

I have two routers, an 1801 which is the VPDN server (and the core for the servers) and an 857W which is the default for the client workstations.

When a client connects to the VPDN server, they are successfully authenticated and assigned an IP address, however they cannot ping or contact anything other than the 1801 and the 857W.

There are a series of servers on the range through to and they all have their default gateways configured as the VPDN routers LAN IP.

The 1801 acts as a DMVPN hub and redistributes routes to the 857W via RIP.

I have eliminated the ACLS by removing them all temporarily, however this has not made any difference.

vpdn enable


vpdn-group 1


protocol any

virtual-template 1

interface Virtual-Template1

ip unnumbered BVI1

peer default ip address pool PPTP

no keepalive

compress mppc

ppp encrypt mppe 128 required

ppp authentication ms-chap ms-chap-v2


interface BVI1

ip address

no ip redirects

no ip unreachables

no ip proxy-arp

ip nbar protocol-discovery

ip flow ingress

ip flow egress

ip nat inside

ip rip send version 1 2

no ip virtual-reassembly

ip route-cache flow

ip tcp adjust-mss 1400

Any assistance would be greatly appreciated as this is now driving me fair up the wall.

Re: VPDN clients unable to contact LAN servers

Running the vpdn clients on a separate subnet produces the same results.
