Re: SMTP Route Through
A few random thoughts
4) Each VPN connection can be either client to your network (software client to firewall/vpn specialty device) or LAN to LAN (firewall to firewall, VPN device to VPN device). Cisco has some very nice options or
there are open source utilities avialable.
5) It depends. I've used X-Windows over 128 k point to point circuit with excellent results. Not sure that a modem connection would support the same. What does "local high performance" mean to you?
Most sites I'm aware of have moved to insisting on VPN connections or allowing limited access from known network addresses.

Re: SMTP Route Through
Here's some HP OpenVMS information on the Communigate Pro package:
http://h71000.www7.hp.com/solutions/mail.html
Information from Stalker:
http://site.stalker.com/news/c-news_article_01252005.html
I'm running a VPN and a firewall that gives me an IP address on the target LAN, analogous to what a DHCP server provides for a secured WiFi connection onto a LAN. Viewed from the perspective of the local network services, the box looks like it's on the LAN.
Typical telnet exposes the username and password credentials in cleartext over the link. ssh is better here.
There are reasonable and inexpensive VPN-capable firewall options available, as well as the commercial offerings across a range of prices.
I can't speak for the current Microsoft Windows clients and options available here as I've migrated off that platform. I do know that there's been a cottage industry in making Windows VPNs easier to use, and I expect there are some reasonable choices available now and Windows Vista or the recently-announced Windows 7 beta may well have improvements in the base OS. Linux on any of the typical HP client boxes also has full VPN capabilities, as does Mac OS X. Any of these client platforms becomes yet easier to deal with when you own the target firewall, too.
And most any remote graphical-based solution based on X or ARD or RDP or VNC does require network bandwidth, yes.

Re: SMTP Route Through
CommunigatePRO does not seem to support OpenVMS, at least it is not mentioned as a supported system
[/quote]
The main pages indeed don't mention OpenVMS as a supported system. However, AFAIK the software is avaialble AND SUPPORTED on OpenVMS. I asked for confirmation.

Re: SMTP Route Through
In the interim, our users access our system through their browsers to perform various functions (development wiki, sales/crm, ...). It seems to be straight forward to write a web based secure script to update the good-clients list as needed.

Specifically what pages are you referring to on our site? I will
gladly report this to our webmaster. OpenVMS is certainly listed as a
platform on the download page for CommuniGate Pro here:

Thank you.

I'd look at OpenVPN which can be configured in routing mode or bridge mode to fit your needs. It's simple to configure in point-to-point mode (for a relatively low number of clients), and a bit more work if you configure it in server mode to accept multiple connections with a single server-side configuration (you need certificates in this case).
I'm not aware of a version of OpenVPN running on OpenVMS so you'd better configure it on the router/firewall or set up a small Linux box within your network to handle OpenVPN.
I use it to connect my home network to the office network (where the tunnel is built up between the routers) and to connect from my notebook while on the road or at a customer site.
Hans.
