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 192.168.1.10 through to 192.168.1.40 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.
ip unnumbered BVI1
peer default ip address pool PPTP
ppp encrypt mppe 128 required
ppp authentication ms-chap ms-chap-v2
ip address 192.168.1.1 255.255.255.0
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.
