You give it a list of networks, and it drops this on the client when it connects. The client will check the list, and if the network is there, will send the packets through the tunnel.

Roaming staff usually needs some form of VPN access, anyway, and even if they don't, this is a great use for one. Put a VPN client on the roamer's computer (Linux, Mac, and Windows 9x/NT/ME/2k all have IPSEC capable clients available), then use the VPN to get back to the mail relay. If the mail relay is behind the VPN tunnel termination point at the server end, then it should only accept mail for relay from valid VPN clients. As such, you solve the roaming staff problem without an open relay. VPN boxes like Ravlin and Nokia Crypto Cluster are cheap enough today that I would consider it a valid cost of doing business if you don't have a better solution.
I have an "operational" question. (SURPRISE! :) VPN solutions are getting inexpensive. However, they are sometimes far from optimal. The VPN solutions I have used (e.g. Bay Networks, MS PPTP) send *every* packet from the end user machine to the VPN end-point, not just selected packets (like with SSH tunneling). This can cause extremely poor performance for some roaming users. For instance, someone in Sydney with a home office in New York trying to get to a Sydney web server suddenly has to make two round trips to New York, just to cross town. Considering trans-pacific fiber congestion and other problems, this can make the VPN nearly unusable. Of course, you could tell the user to turn off the VPN, but you try to explain to a typical end user when he should and should not have the VPN turned on, or that he cannot send mail while browsing the web, or things like that. So, does anyone know of a VPN that does selective forwarding like SSH tunneling?

You have to balance that desire against your users' generally unspoken requirement that your service be functioning, usable, and able to deliver mail to its' final destination. If this were any other kind of service that commonly requires user authentication (accounting, data storage, etc.) there wouldn't even be a question.

Depending on requirements, isn't the whole idea to put the email into the tunnel? That's why this thread came up in the first place. BTW, SSH tunneling can drop every packet through the tunnel with a forward-all config. it isn't even very hard and can be done with a Win client, using F-Secure. In fact, sometimes that works, when PPTP doesn't, in Windows-hostile environments (*nix bigots sometimes do everything they can to screw up Win machines). However, none of it works when port 22 is blocked by the firewall.

You *can* do all that. I prefer SMTP AUTH to POP-before-SMTP because PbS leaves a small vulnerability on your mail server - very small, but it exists nonetheless. But many providers use PbS too. If this whole issue cropped up because you wanted to provide roaming access to your mail servers, those are two very widely-implemented solutions. If you want, I can even offer some help getting it set up as I have had a longstanding policy of offering relay-closing help at no charge to ISPs who need it.

This is nonsense...most of us "go after the actual spammers" as best as we can and the law permits us. If you supply plastic explosives to terrorists with no checks, you may not be directly responsible for their actions, but you are certainly part of the problem. If you have an open relay, you are a big part of the spam problem, whether you like it or not.

What does "america" have to do with it? Open relays are all over the place, and a big PITA. Refusing your mail is *my* right, as owner of my network; and also my responsibility. Of course it is your "right" to have an open relay if you like, just don't expect everyone else to accept email from it.

If you want a huge laugh, (and want to give ole Mitch the /. or NANOG effect) go check out http://www.netside.net/sys.html
"Network and Communications NetSide is connected directly to the Internet backbone via a high speed point-to-point full T1 link (1.544 Mbps) into the MCI backbone (at Pompano Beach). A Cisco 4000 router is used to direct the in-house Ethernet TCP/IP network traffic to and from the Internet. To help reduce the network load and improve performance, two Ethernet 10-BaseT interfaces, connected to separate AT&T StarLAN 10 hubs (with blinking lights :-) forming in effect subnets, are used on the servers. Each subnet connects to a different Ethernet port on the Cisco router."
That's some FAT pipe you have there Mitch. What EVER do you do with your spare bandwidth? heheheh And your network just blows me away. I love the "To help reduce the network load" part. Where's the load? You've got serious issues if you can't pass a DS1 worth of traffic without your net melting.
"Emergency Provisions Besides redundant servers, NetSide is also prepared to operate in emergency conditions, such as city-wide power failures as experienced during Hurricane Andrew. Housed in a solid concrete block structure, we don't expect heavy storm damage to occur. Our fiber rack (for telephone and data lines) has 3 rows of battery backup rated for 8 hours of continuous operation. NetSide owns 2 emergency generators: an extended-run heavy-duty Coleman Powermate Vantage (14HP 2cyl electric start gas engine - 7000W), and a portable medium-duty Dayton (5HP gas engine - 2200W)."
Wow! So, you've got enough generator to power the lights, soda machine and coffee maker. You gonna invite all the customers to your site and sit around and watch the servers not run drinking soda and coffee? Sounds like fun.
Mitch. You're an END USER. Sure, you sell dialup access. You couldn't do much more with that big FAT DS1 you've got. You're an END USER.

You see, if you were a real network operator:
(1) That would be more than a DS1. (2) The last hop wouldn't show up with the ASN of your upstream. (3) The last hop would RESOLVE in in-addr.

It might be a good idea to register some in-addr resolution servers for that block there Mitch.

Gilmore" on Mon, 28 May 2001 01:24:58 EDT:
The VPN solutions I have used (e.g. Bay Networks, MS PPTP) send *every* packet from the end user machine to the VPN end-point, not just selected packets (like with SSH tunneling).
This should be configureable, if it isn't then maybe it's time for a switch in protocols/software. :-)
So, does anyone know of a VPN that does selective forwarding like SSH tunneling?
FreeS/Wan does this by default. Only traffic defined by the tunnel security association is encrypted, the rest goes through untouched. Very optimal. :-) I don't believe this is specific to FreeS/Wan either, as most IPSEC implementations I have seen do something similar. (including hardware solutions).

Most competitive vendors now provide native and upgrade provisions for QoS in one form or another. The problems most often encountered revolve around multi-vendor cos/qos feature implementation incompatibilities. The "least common denominator features" that are needed for basic interworking usually do not extend to 'differentiating' features that vendors like to hold close to the vest, such as prioritization and cos/qos features. Not without much grief, in any event. It forces one to seriously consider single vendor solutions. fwiw. - ------Original Message------ From: Sean Donelan <sean@donelan.com> To: nanog@merit.edu Sent: May 29, 2001 6:17:46 AM GMT Subject: QOS or more bandwidth While its generally more effective to add more bandwidth than rationing it with QOS, with the recent downturn in capital markets will QOS become more popular?

It's a 1995 page which hasn't been updated in ages. I didn't even remember it was still live. But at least it proves NetSide was around in those times. Let's see, I have a copy of a uu.net active file, dated Jan 6, 1996. At that time, they were the norm. It contains 13090 lines. You do the math. File URL http://www.dotcomeon.com/active.uunet I responded to Wilcox and Fraizer in private. Their bashful posts serve to illustrate exactly why such people cannot dictate policy to others. There is one lesson to learn from this. We have reached a stage where the rights of an individual or entity to existence in cyberspace need to be protected under the law. You may take the lead in applying democratic principles that follow the real world laws, or the legislature will do it ad hoc. - --Mitch NetSide ------------------------------ Date: Tue, 29 May 2001 06:28:42 -0400 (EDT) From: John Fraizer <nanog@Overkill.EnterZone.Net> Subject: Re: Mitch tries to defend his open relay again (was Re: ORBS (Re: Scanning)) On Tue, 29 May 2001, Mitch Halmu wrote:
