We have a SOHO setup with Windows 2008 Server as DC.
The Server is configured as VPN Server as well (PPTP)
The setting was working perfectly and we had remote access outside the LAN through VPN to the internal resources.
For some reason the DSL router was reset to factory defaults.
Later everything is working apart from VPN. Both VPN Passthrough and Port forwarding have been configured but of no use.
VPN can be connected through local Ip but not through WAN Ip.
