Hi all, I am sure this is something that a reasonable number of people would have done on this list. I am after a LSN/CGN/NAT444 solution to put about 1000 Residential profile NBN speeds (fastest 100/40) services behind. I am looking at a Cisco ASR1001/2, pfSense and am willing to consider other options, including open source.... Obviously the cheaper the better. This solution is for v4 only, and needs to consider the profile of the typical residential users. Any pitfalls would be helpful to know - as in what will and and more importantly wont work - or any work-arounds which may work. This solution is not designed to be long lasting (maybe 6-9 months)... it is to get the solution going for up to 1000 users, and once it reaches that point then funds will be freed up to roll out a more robust, carrier-grade and long term solution (which will include v6). So no criticism on not doing v6 straight up please. Happy for feedback off-list of any solutions that people have found work well... Note, I am in Australia so any vendors which aren't easily accessible down here, won't be useful. ...Skeeve *Skeeve Stevens - *eintellego Networks Pty Ltd skeeve@eintellegonetworks.com ; www.eintellegonetworks.com Phone: 1300 239 038; Cell +61 (0)414 753 383 ; skype://skeeve facebook.com/eintellegonetworks ; <http://twitter.com/networkceoau> linkedin.com/in/skeeve experts360: https://expert360.com/profile/d54a9 twitter.com/theispguy ; blog: www.theispguy.com The Experts Who The Experts Call Juniper - Cisco - Cloud - Consulting - IPv4 Brokering
