ROS 4.6
I have a client that urgently need a VPN connection to their local network.
The thing is that we NAT our wireless network(to 10.0.0.0/8 range), and then each client site also has a Mikrotik that NAT their local LAN to 192.168.0.0/24
What they've done is to setup a Windows XP 'Allow incoming connections' setup, a crude VPN version.
What I've done so far:
On CPE:
Forwarded TCP port 1723 to LAN IP
Forwarded GRE protocol to the LAN IP
On our breakout router:
Forwarded TCP port 1723 to WLAN IP
Forwarded GRE protocol to the WLAN IP
From within our WLAN it seems to want to connect (they do not want to give username/password!) as it says username/password is incorrect, but from outside the network, it does not want to, just says connection cannot be established.
Please help to either fix the messy scenario as-is,
or, preferably,
Would there be an easier/better way to setup VPN on our breakout router that in some way connect directly to the client's LAN through it's NAT?
I hope this makes sense.
