VPN Behind Century Link C1000A Modem / Router VPN not working
I am trying to help a sister company implement VPN for Client-to-Lan but unfortunately they have a Century Link C1000A modem/router that does not appear to support bridge mode. Does anyone have any experience with this? I have forwarded ports 500, 1701 and 1723 but I can't figure out what else needs to be set.
Configuration is: (external IP) --> Century Link Modem (LAN: 192.168.1.1) --> (WAN: 192.168.1.30) TL-R600VPN (LAN: 192.168.68.100 DHCP enabled 192.168.68.x) --> nodes
Attempting to connect via L2TP yields error 809 Attempting to connect via PPTP yields error 806
Thanks for any help. Scott
