Well, it's a little more complicated than the above description.
I have a hotel that wants broadband access to all their rooms for guests. Unfortunately, most business guests connect to their office using VPN. Well, SOHO equipment isn't going to cut it because each one of these "guests" uses something different (checkpoint, mschap, pptp, blah, blah, blah). It would also be impossible for me to get a hotel guest to give me the number to their company's IT department so I could try and convince them to let me know what ports their VPN operates over so that I could open a port tunnel for them. Sheeesh...
Past my small office networking experience, I'm fairly clueless. What equipment, if any, would allow me to circumvent manual port tunneling and let these people use their VPN across broadband behind a router issuing DHCP addresses? layer 2, layer 3, VLAN (what is all this stuff?)
If someone could point me in the right direction then I can "bone up" on the self education.
