Microsoft Windows™

Windows network kernel will also propagate packets sent by VAX MP to the host network stack and vice

versa.

If there are multiple instances of VAX MP or other SIMH simulators or other virtual machines running on

the host and bound to NIC,

pcap will also provide an interchange of packets between them.

If you are using a firewall, remember to configure the firewall so it allows required connections to/from

addresses of the added VAX instance or instances.

(Intra-host connection set-up)

It is also possible to set up a connection between VAX instance and host only and/or other virtual

machines running on the host:

Install Microsoft Loopback Adaptor

. Microsoft Loopback Adaptor is virtual Ethernet adapter simulating

Ethernet connection (virtual wire) between host machine and applications using the adapter. Third-

party virtual Ethernet adapters with similar capabilities can also be utilized instead.

Bind IP address to MS Loopback Adaptor in the adapter’s properties. This address establishes host-side

IP address of the adapter.

Edit VAX MP startup script to attach VAX MP DELQ/DEQNA controller to the adapter:

set xqb enabled

set xqb mac=08-00-2b-aa-bb-c2

set xqb type=delqa

attach xqb MS Loopback adaptor

By the way of example, let’s assume MS Loopback Adaptor is assigned IP address 192.168.3.1 on the

host’s side. Then while configuring TCP/IP Services for OpenVMS you can define interface QE0 (bound to

XQ) to have IP address 192.168.3.200:

$ TCPIP SET INTERFACE QE0 /HOST=192.168.3.200

$ TCPIP SET CONFIGURATION INTERFACE QE0 /HOST=192.168.3.200
