-> So I'm running Windows XP inside a VirtualBox.
-> MajorBBS wants to know the IP Address,Local Network Mask, Gateway IP
-> Address, Primary domain name server, and secondary domain name
-> server.
-> The ipconfig /all reports an ip address of 192.168.0.77, gateway ip
-> address as 255.255.255.0, prim domain name server is 192.168.0.1 and
-> the same for the secondary.
-> The main ip address coming into the router is 76.156.142.14.
-> I have opened port 23 on the router and the firewall.
-> I sill can't get it to accept any income telnet calls.

    Not sure if you tried to set up port forwarding in the VM. Network
advance settings. This will setup forwarding from your host machine to
the Guest. I had to do this when transfered my bbs setup to VitrualBox.
I notice the connection getting to my main system (host) but not
reaching inside the VM (guest). I set the port forwarding and PCBoard
accepted the connection within the VM.
