Normally I would agree with you as far as separate instances, however this will be in a situation where we pay ridiculous amounts for cpu and memory, so a single instance is what we are shooting for (remember those ridiculous requirements).

The number of random bugs I've hit with their software are numerous. In the right hands, it's a powerful tool. And it seems to fit your solution really well. If I were in your shoes, I would install two instances that would handle the "edge" of the cluster, and then an instance per customer (lightweight, they sell a VMWare image).

Howdy, I am looking for something a little unique in a bit of a tough situation with some sticky requirements. First off, my requirements are a little weird and I can't bend them a whole lot due to stipulations being put on me. I am in need a firewall appliance which can be run on VMware vSphere, with IPSEC support for multiple Phase 2 negotiations within a single Phase 1. I am also in need of something that can support VLAN interfaces on the LAN side, and ideally something with multi zoning so I can keep LAN side networks separate from each without ridiculous firewall rules. Meaning build a zone for "Customer network 1" and it displays separately (ease of management and firewall config hopefully). I need a minimum of 10 "zones" on LAN side (/29 or /30), and NAT support for LAN to WAN (to dedicate all outbound connections to a single IP from a specific zone), ideally something extremely scalable (100-200 zones). And here is the super fun part! I need something that is going to be web managed primarily as minions will be doing most of the day to day maintenance, or very simple CLI config. Willing to pay for something if need be, but looking for something that can easily handly 50-100mbit of throughput. Any Ideas? Thanks! Blake Pfankuch

cheapo UUFB solution for Cisco 7201

I've got a Cisco 7201 with about 500 L2TPv2 tunnels, and I suspect that UUFB (unknown unicast flooding) is resulting in spiking (I put an ACL on to kill broadcast traffic, so I'm sure that's not related). I've googled and don't see anything for the 7201, just the 7600 series. :/ i.e. http://www.cisco.com/en/US/docs/routers/7600/ios/12.2SR/configuration/guide… Anyone have any suggestions on (something cheap) that I can put in front of this box to spare it from (what I suspect) is a gateway that unicast floods when a MAC address has aged?

Looking for tw telecom folk to resolve IPv6 access to their site
by Frank Bulk 02 Jul '11

02 Jul '11

IPv6 access to TW Telecom's website, www.twtelecom.com, has been down almost continuously since Wednesday evening. For dual-stacked users browsing their site but not using Google Chrome this can results in timeouts. I reached out to their NOC twice. The second time the site did come back up for a few minutes, but then went down again. Is anyone from tw telecom on this list that can resolve this, or can forward this to a contact? Logs below (Central Time).

What do you think about the Juniper MX line?
by Chris 01 Jul '11

01 Jul '11

Hello, I've been doing some research into using the MX line of Juniper routers and was interested in hearing people's experiences (the good, bad, and ugly). What do you like about them? What do you dislike? Where are you putting them in your network? Where are you not putting them? Why? What other platforms would you consider and why? I hope to hear some candid responses, but feel free to respond privately if you need to. Thanks!
