I have been doing this for some time now with the only difference being that the link protocol is PPP on KA9Q. A list of public PPP implimentations is included below. One area that has some options is how your home PC looks to the rest of the world as represented by the office PC. One option is to assign a subnet to your home PC (and any other hosts that connect through the office PC). The office PC then needs to advertise that subnet to the world. In KA9Q we use RIP. This is the method we use for our PPP servers (also PCs running KA9Q) that many campus people dial into. If you do not want to use a whole subnet when just one host is connecting through the office PC, you can use proxy arp. In this case your home PC has an IP address that is on the office subnet and the office PC will arp for both itself and for the home PC. This can be done in KA9Q by making a manual entry in the office PC's arp table. This is the method that I use for the PPP connection directly to my office PC rather than through the campus PPP server. BTW, with the latest KA9Q PPP implementation, the PPP servers and office PC assign the home PC's IP address at connection time based on the authentication, so I don't have to worry about making configuration changes on the home PC no matter which one I dial up. Here is the list of public PPP implementations of which I know.
