How do I run DOS TCP/IP or packet-driver apps in DOS sessions?

Originally I thought MS’s TCP/IP would allow for DOS apps to use 32-bit TCP/IP in the same way IPX apps would (such as NetDOOM or Descent), but some TCP/IP apps provide their own complete TCP/IP stack, and use the pure packet interface (characterized by Packet Drivers that leave transport protocols to the apps themselves). There’s an NDIS 3.0 packet driver you can install as a Win95 “protocol” at ftp://nic.switch.ch/mirror/novell/drivers/ndis3pkt.zip which provides the packet driver interface for any network card. The driver is re-entrant so multiple DOS sessions can access it. The big catch is, if you use MS’s TCP/IP Protocol at the same time, AND you have DOS packet apps that provide their own TCP/IP stack, you cannot have MSTCP and the packet app use the same IP address. You are effectively running two TCP/IP stacks (one for Winsock apps and the one provided by the packet app) and these can’t have the same IP address. However, multiple DOS sessions running TCP/IP packet apps can use
