Configuring access from OpenVMS x86-64 to company intranet via Windows VPN

Post by volkerhalle » Mon Apr 17, 2023 4:29 am

If running a VSI OpenVMS x86-64 system at home using Windows and VMware workstation and trying to set up easy communication to your company's OpenVMS servers in the intranet via a VPN connection, here is a description on how to do this:

Code: Select all

NOTE: IP adresses are examples and need to be adopted according to local config

Windows: ipconfig -> find IP address if VMnet8 adapter -> 192.168.199.1

VMware Workstation Player: -> configure network interface as NAT (VMnet8)

OpenVMS x86-64:

@TCPIP$CONFIG
		-> Optional components -> configure PWIP
		-> Core components -> domain -> same as used in company intranet
		-> Core components -> interfaces -> 192.168.199.192/24
		-> Core components -> routing -> 192.168.199.2 (.2 is important)
		-> BIND resolver -> configure DNS servers from company intranet

@NET$CONFIGURE	-> Directory services to use: local,domain
		   LOCAL: LOCAL:.nodenm
		   DNS/BIND: nodenm.domain

Test DECnet-over-IP locally with $ SET HOST localhost

Start VPN to company intranet and wait a minute...

$ TCPIP PING some-node-in-company-intranet
$ TELNET x.x.x.x	(IP address of some OpenVMS server in company intranet)
$ SET HOST IP$x.x.x.x	(IP address of some OpenVMS server with DECnet-over-IP)
$ SET HOST FQDN-of-VMS-server-with-DECnet-over-IP

You now can transparently access the OpenVMS servers in the company intranet,
which have been configured to use DECnet-over-IP with all possible OpenVMS
x86-64 tools, which use RMS-based file access.

You can also define DECnet proxies on those OpenVMS servers:

UAF> ADD/PROXY IP$192.168.201.1::user local_user [/DEFAULT]

192.168.201.1 is the IP address of the 'PPP-Adapter VPN-xxx' adapter on your
Windows system.

Configuring access FROM the company intranet TO the OpenVMS x86-64 system 
running at home on VMware Workstation Player requires a PRO license, to be able 
to use the VMware Virtual Network Editor to define port mapping on the VMnet8 
adapter 
Enjoy,

Volker.

works fine except if company filewall does not allow ports 102 nor 399 ;-)
