I'll put a final draft up on the realitycheckBBS.org web site, but here's 
what I've got so far. It's finicky, sometimes DHCP will fail 3 times out of 
4, but work the 4th time.


   +------------------------------------------------------------+
   | CONFIGURING DOSBOX with NE2000 emulation and mTCP software |
   +------------------------------------------------------------+


1. Find a fork of DOSBOX that supports the NE2000 patch. I used DOSBOX-SVN 
Daum from 2014, which allegedly is less buggy than the 2015 version.

2. Confirm the following section in your dosbox.conf file:

[ne2000]
#  ne2000: Enable Ethernet passthrough. Requires [Win]Pcap.
# nicbase: The base address of the NE2000 board.
#  nicirq: The interrupt it uses. Note serial2 uses IRQ3 as default.
# macaddr: The physical address the emulator will use on your network.
# realnic: Specifies which of your network interfaces is used.
#          Write 'list' here to see the list of devices in the
#          Status Window. Then make your choice and put either the
#          interface number (2 or something) or a part of your adapters
#          name, e.g. VIA here.
ne2000=true
nicbase=300
nicirq=3
macaddr=AC:DE:48:88:99:AA
realnic=list

3. Install WinPCAP from https://www.winpcap.org/. This software is no longer 
supported, but I couldn't get npcap, the replacement, to to work.

4. Run DOSBOX and look in the status window. You should see a list of 
network interfaces like so:

Network Interface List
-----------------------------------
 1. rpcap://\Device\NPF_{02C5160E-3B81-40F1-BF97-EC9384205B78}
    (Network adapter 'VMware Virtual Ethernet Adapter' on local host)

 2. rpcap://\Device\NPF_{33E4D987-523A-4803-978F-4C78A0E1CDDD}
    (Network adapter 'TAP-Windows Adapter V9' on local host)

 3. rpcap://\Device\NPF_{37DAC71E-9617-4516-87DE-F2DCB425E1D6}
    (Network adapter 'Realtek PCI GBE Family Controller' on local host)

 4. rpcap://\Device\NPF_{157C99AB-2743-42D2-B58D-C33195E00FE1}
    (Network adapter 'Microsoft' on local host)

 5. rpcap://\Device\NPF_{FDD94540-D88C-4E05-A0D5-C14C35421D81}
    (Network adapter 'VMware Virtual Ethernet Adapter' on local host)

5. Edit the [ne2000] stanza in your dosbox.conf to read "realnic=. Exit DOSBOX.

6. Download the Crynwyr NE2000.com packet driver from 
http://crynwr.com/drivers/ to your DOSBOX drive.

7. Download the MTCP suite from https://www.brutman.com/mTCP/mTCP.html. 

mTCP is a set of TCP/IP applications for personal computers running PC-DOS, 
MS-DOS, FreeDOS, and other flavors of DOS. The applications include:

DHCP: a DHCP client for auto-configuring your machine for use on your 
network.
FTP: an FTP client for transferring files across the network at high speed.
FTPSRV: a high performance FTP server that allows multiple connected 
clients, a sandbox area for untrusted users, etc.
HTGET: the HTGet program for downloading files/content from web (HTTP) 
servers
HTTPSERV: an HTTP server supporting HTTP 0.9, 1.0, 1.1
IRCJR: the IRCjr IRC (Internet Relay Chat) client for chatting on IRC 
networks.
NC: the Netcat command which can be used to send and receive data easily 
across a network.
PING: the Ping command for checking basic network connectivity.
PKTTOOL: A packet sniffer and diagnostic tool for packet drivers
SNTP: an SNTP client for getting the current date and time from public 
servers on the Internet.
TELNET: a Telnet client for connecting to Unix systems, BBS systems, or any 
computer that supports Telnet.

Copy the files to a folder \mtcp in your DOSBOX drive and in the 
mtcp\samples\ folder, copy the sample .cfg file to your \mtcp directory. 
Edit the file to suit your configuration, and add SET MTCPCFG= to the autoexec section of your DOSBOX.conf.

8. Re-run DOSBOX. From within DOSBOX, run the following commands:

C:\>NE2000 0x60
Packet driver for NE2000, version 11.4.3
Packet driver skeleton copyright 1988-93, Crynwr Software.
This program is freely copyable; source must be available; NO WARRANTY.
See the file COPYING.DOC for details; send FAX to +1-315-268-9201 for a copy.

System: [345]86 processor, ISA bus, Two 8259s
Packet driver software interrupt is 0x60 (96)
Interrupt number 0x9 (9)
I/O port 0x300 (768)
My Ethernet address is AC:DE:48:88:99:AA

(The line above should correspond to the macaddr entry in dosbox.conf)


C:\>DHCP
mTCP DHCP Client by M Brutman (mbbrutman@gmail.com) (C)opyright 2008-2020
Version: Mar  7 2020

Timeout per request: 10 seconds, Retry attempts: 3
Sending DHCP requests, Press [ESC] to abort.

DHCP request sent, attempt 1: Offer received, Acknowledged

Good news everyone!

IPADDR nnn.nnn.nnn.nnn
NETMASK nnn.nnn.nnn.nnn
GATEWAY nnn.nnn.nnn.nnn
NAMESERVER nnn.nnn.nnn.nnn
LEASE_TIME 86400 seconds

Settings written to 'c:\mtcp\mtcp.cfg'



At this point, the MTCP suite should work.
