RE: cpu needed to NAT 45mbs
The important thing to remember is that when you exceed 20 to 30 wireless users in a small area, your now dealing with an 'Enterprise' deployment. Lots of whitepapers exist on this subject. Design your layer 2 stuff correctly, and use L3 gear that is up to the task. If you're trying to use Linksys wireless routers to handle 400 users, you may as well try to invade a foreign country with lawn darts and a squirt gun.

Everyone I speak to says something along the lines of "Why would I put that sort of stuff up? I want people to pay me for that kind of clue." There are slides covering basic stuff and observations out there. (I'm going through a wireless deployment at an ISP conference next week; I'll draft up some notes on the nanog cluepon site.) Adrian

> So where's the ticket then? It's perfectly reasonable to expect some sort of detail since our attendance fees help fund the operation of the list. There's an issue with the complexity of the delivery system that has developed over time and some new anti-spam appliances that have been implemented. It's causing some difficulties in resolving the issue and it's being worked on. We tend not to get bogged down in the technical minutia with the Merit admin team since we have day jobs, they get paid to do this work, and too many cooks in the kitchen are usually not helpful and the Merit folks are as competent (or more in some cases) as any of us. We'll keep you posted and do a post mortem. Best Regards, Martin Hannigan NANOG MLC Member

OT: Can a MSN/hotmail.com email admin contact me offlist?
We have been having difficulty sending email to hotmail.com email addresses. This started several weeks ago and was tracked to a computer computer that was indeed sending out spam - but has since been resolved. Normal measures to contact MSN/Hotmail have gone nowhere. We've received the run-around from their support drones.. They've even went so far as to silently drop all email (while reporting successful delivery). We've submitted the forms at their postmaster.live.com site (and been rejected). Oddly enough - the servers that they are blocking don't show up on their SNDS service. Please contact me offlist so we can get this resolved. -- Thanks, - Joseph W.

[admin] Errors to NANOG list subscribers take II
Dear Colleagues: As you know, we are all seeing a single mailer message show up in our mailboxes at ~0330/est on a daily basis. We are aware that this is on-going. The issue is being actively worked on by the admin team at Merit and a resolution is forthcoming. Since the message happens once a day, it's understandably difficult to make a best effort determination that a fix will take hold. There isn't a test or dev system to try out solutions. This problem has been assigned a reasonable priority by the folks at Merit and we hope to see it fixed soon. Thanks to all who have let us know about this.
