It's a long story that I will spare you from hearing - But I have a network, several actually, that will be connecting to a Windows 2008 R2 server at a data center using SSTP. RRAS is installed on the server and I can connect flawlessly with any Windows client and ping the private IP address of the server. The public IP is basically firewalled off from anything other than 443 - and even then only from the static publics of these few networks.
I have created an SSTP Client Interface under PPP and it too can connect to this server. It also gets a private IP on the same subnet as the private IP of the server. If I use the ping tool on the Mikrotik and specify the SSTP Client interface, I can ping the private IP of the server. However when I ping from any machine behind the Mikrotik I get nothing.
I have created a route to the remote subnet using the SSTP Client interface as the gateway, seems to make no difference.
192.168.2.0/24 (LAN) -- 192.168.2.1 (Mikrotik) -- 192.168.253.11 (SSTP Interface) ----TUNNEL----192.168.253.1 (Remote Server)
I also made sure to add a NAT rule that traffic from 192.168.2.0/24 bound for 192.168.253.0/24 is 'Accepted' so it didn't get NAT'd.
What Am I missing to get traffic from the .2 to .253 subnet??
