Re: [nznog] Web Servers: Dual-homing or DNAT/Port Forwarding?

Wotcha, >Number 1 gets you thinking along the IPv6 route (no pun, and imho :) ) >since you have to treat each boxes as if it was public. I see this kind of statement surprisingly often. Having a public address doesn't make a device public. I don't really see a drive to have devices exposed to the internet without a stateful device in front of them in IPv6 world. People shouldn't allow unsolicited connections to hit your internal workstation on any address scheme. Cheers, Alex.

Message-ID: <52A5F649.7070904(a)insync.za.net> Content-Type: text/plain; charset="iso-8859-1"; Format="flowed" Hi, I normally use a combination of "1" and "2". I prefer 1 for weird and "not nat friendly" protocols, like SIP or some other application. The general rule of thumb is to use number 2 in other cases. In both setups, remember to deploy local firewalls as well. This will help for the case when a box on the subnet is hacked. My other twist is to deploy "1" without the private NIC, along with local firewalls (and as you said, dedicated FW). Number 1 gets you thinking along the IPv6 route (no pun, and imho :) ) since you have to treat each boxes as if it was public. Cheers, Pieter

Cogent & Level 3 routing issue?
by Matthew Crocker 10 Dec '13

10 Dec '13

Anyone seeing issues between Cogent & Level3 in NYC? I have Sprint & Cogent for bandwidth. Everything has been humming along for a couple years just fine. Yesterday around 8:00AM my BGP session with Cogent flapped. Now, when my Cogent BGP is up I get 100% packet loss in level3 land. When Cogent BGP is down (i.e. I’m running solely on Sprint) Everything is fine. I have an open ticket with Cogent. They say they have a ‘capacity issue’ with level3 that has been escalated to executive levels. With Sprint & Cogent BGP UP I see traceroutes showing traffic leaving me on Sprint but returning on Cogent (and failing at level3). I’m guessing it is the level3/cogent border With Sprint UP & Cogent Down I see trace routes showing traffic on to/from on Sprint just fine. Anyone else having issues? -Matt -- Matthew S.

Network Lifecycle Management - anybody???
by Stefan 09 Dec '13

09 Dec '13

As $subj may infer, do you guys follow any type of network lifecycle in your environment? If so - what would be some criteria you would consider critical: - consistent rate of cash flow, year after year, while replacing aging gear (allowing for consistent budgetary planning) - risk reduction while replacing unsupported equipment - security issues associated with OS or appliances not supported - business / apps demand for capacity or features (e.g. virtualization, SDN, etc.), laid out well in advance to allow for a 3-4-5 yrs plan with a consistent replacement rate of aging equipment - increased costs of support for aging equipment, or recertification for vendor support - anything else ... ??? Care to share some [other] aspects, as they may relate to $subj? Thanks, ***Stefan

My conclusion is that Apple does not yet support IPv6 in any fashion for Wireless Guest networks. James R. Cutler james.cutler(a)consultant.com
