    Does anyone know if its possible to configure port forwarding on a Cisco 837 adsl modem/router and if so how is it configured. I want to use OpenVpn to set up a secure VPN. The Cisco 837 is on one of the nodes.

    Set "ip nat inside" on your internal interface and "ip nat outside" on your external interface. Then you can forward a port for openvpn as follows:
    ip nat inside source static udp 192.168.x.x 1194 interface zz 1194

    zz will be your external interface (the one set as ip nat outside).. x.x will obviously be your internal ip address.
