Remote Access - can ping between but not outside.

PPP connection over TCP/IP established over modem between home (Windows95) and work (Digital AlphaStation 200 4/100 running Digital Unix 3.2G).

I can ping/telnet from home to my work PC and vice-versa.

I CANNOT ping/telnet from home through my office to another workstation on the same subnet...so I also cannot ping the gateway router to to rest of the network...from home.

I CANNOT ping/telnet from any other workstation on the same subnet at work through my workstaion in my office in which my modem is connected to home.

I am always using the IP address.

I have researched this problem for many months and consulted the MAN pages as well as networking/TCP/IP books.

I need my workstation in my office to recognize that it needs to listed for my home PC's IP address in addition to its own and pass that information on to my home PC and vice-versa.

I though I could do it with ARP...but I am unable to determine the MAC address for my home PC since I am not using a network card...but am using Dialup Networking.

I have read that perhaps I need to add an additional IP address for the PPP to the host table in addition to my home PC IP address and somehow use that additional address to "bind" the two together ...in some sort of routing table or something like that.

Any time I need to get a file or something, I have to log onto the office PC from home first and then ftp from there.  Then I can ftp from there to home or vice-versa.

Thanks in advance for your help,
