Have a look at the VPN client at http://www.shrew.net/, it is a
standards compliant IPSEC VPN client that interoperates with open
software IPSEC implementations - I have not tried it with OpenBSD but
I imagine that it will Just Work(tm).  The license is reasonably fair though
restrictive and you can create an "install" bundle that will pretty much
auto-configure the client with only a small amount of prep work which
makes the window side deployment very simple.  The only issue I have
had was the dead peer detection was a little too aggressive for some
of the people I was using this with - just turning this off on the
client side fixed the problem.

For my Windows users i setup OpenVPN in server mode. No problem at all for
roaming users, the same crypto algorithms for Windows and for UNIX. User
just starts .bat file and gets VPN.
I think IPSec is not so good for Windows users because of limitation of crypto:
3des, sha1. It's not so hard to setup, but also i faced problem if office
network is located behind NAT. Also i didn't find thing similar to srcid on
Windows side.

As long as i use OpenBSD at home i'm trying to setup IPSec tunnel for myself.
But still don't resolv a problem :)

VPN suggestions and advise for clean sheet setup

2008-02-29 Thread Daniel Ouellet

Hi,

I have been looking into this for some time, but there is so many 
different setup possible that unless you have one and are force to 
continue using it, one wouldn't know witch way to go.


I try to keep it as simple and clean as possible, so if you start with a 
clean sheet and no restrictions on use, what would you suggest to go with.


Requirements are to sadly connect Windows users back to a network and I 
want that box to be OpenBSD, or multiples OpenBSD boxes to get full 
network access from these connections. Multiple at once and I try to 
keep the management of the users as simple as possible.


I guess using the pptp client from Windows, or their remote office 
built-in XP. I have to say, last time I use any Microsoft PPTP client 
was about 12 years ago in the NT 4 service pack 6. That's how old it 
was. I only use ssh, putty if needed at time from Windows and that's all 
I need.


I think you could say, it's time to come to sync with todays needs for 
Windows I guess.


What would you suggest to use if any choice is possible? I know OpenBSD 
redesign the ipsec, but is that the best way now? Looks like many users 
still use OpenVPN, and a bunch of others. I am a bit at a lost as if 
that's best, why so many variation in use still today in the archive and 
why one would go that path. I would love the "KISS VPN" I guess. (;> 
Even connecting office together, I see many different choices in the 
archive.


Three needs, providing access to remote Window users, browser, etc.

And if possible in some cases providing specific network access via VPN 
(tunnel, or what not) to remote office.


Last, would be to provide streaming access via a secure gateway like 
proxy or the like to traveling users.


The solutions for each one could be different, but using the same setup, 
or part of it anyway would obviously be better.


The goal is the minimize the impact and most importantly support and 
problem on the remote Windows users, witch I admit, may not be that 
easy. (;>


There is so many different choices and ways to do this now, witch one 
would you recommend if today you could start with a clean sheet and not 
have to be stuck with legacy setup?


Many thanks for the suggestions.

Daniel
