When I try to us the automated form to unblock my server's IP I get: ******* 67.22.175.244 We have received your request for removal from our inbound blocklist. After investigating the issue, we have found that the IP you provided for removal is currently not on our blocklist. We need the IP address currently blocked to further investigate this issue. The IP address is a number separated by decimals and is located in an error code starting with "550" in the returned email from Comcast. Please verify the IP(s) and resubmit your request to http://postmaster.comcast.net ******* and yet I consistently get: Remote host said: 554 Transaction Failed Spam Message not queued. when trying to send any email from the above mentioned IP. Please contact me via efinley at emerytelcom.com (from a non comcast address so I can email you back) or directly @ 435.636.0069 Thanks, Elliot

It's usually easiest if you have a server as your gateway for the local network too, that'll permit some more granular allowances with the ips, forwarding, etc. OpenVPN is a pretty good daemon for the tunnel. The only thing to keep in mind with the dynamic ips is once in a blue moon (for my area at least) you'll pick up a new ip and have a brief period of packet loss as the vpn re-establishes.

Update from the NANOG Communications Committee regarding recent off-topic posts
by Matt Griswold 02 Aug '12

02 Aug '12

As a quick update, we've implemented some list settings last week to help to keep spam off the list. New subscribers are moderated until we're comfortable with their posts. We rejected the idea of keyword based message filtering since not only is a lot of work to maintain, it's trivial to get around it if you really want to post banned words. Comments and suggestions are welcome. Matt Griswold, on behalf of the NANOG Communications Committee

Fwd: Re: DOCSIS 3.0 & PPPoE/L2TP compatibility
by Scott Helms 02 Aug '12

02 Aug '12

I've actually run into this specific problem and the issue your running into is that at no time was PPPoE part of the DOCSIS specification. It was supported on several CMTSs because the Cisco UBR shares much of its OS with more mainline Cisco routers which support L2TP and a host of other non-DOCSIS related protocols. It was also widely supported on some of the earliest CMTSs which were bridges instead of routers (then you needed a separate box to be the LNS). The real problem isn't a change in DOCSIS version but that they choose a platform that doesn't share a code base with a general purpose router. This could have been happenstance or by design, but I can tell you your chances of getting PPPoE to work at all on that platform (even for the cable operator) are not high because the box will not operate as a bridge and there is no (AFAIK) way to relay the PPP discover packets.

Is Hotmail in the habit of ignoring MX records?
by Lou Katz 02 Aug '12

02 Aug '12

One of my users has reported incoming mail failures, which I finally tracked down. It turned out that Hotmail has seen fit to send the mail to his domain's A record machine, despite the fact that he has valid MX records. The A record points to my webserver, which does not normally accept mail for anyone. The mail server MX records are to an entirely different machine. Comments? Do I need more valium? -=[L]=- --

Level3 (3356/3549) changes routing policy
by Fredy Kuenzler 02 Aug '12

02 Aug '12

From my observation Level3 has recently changed their routing policy. It seems that 3356 always prefers customer prefixes of 3549, regardless of the AS path length. Example (seen from 3356): 3549_13030_[Customer1]_[Customer2] is preferred over 2914_[Customer1]_[Customer2] Considering that both 2914 and 3549 are peers of 3356, and 13030 is a customer of 3549, 3356 seems to give higher local-pref on the longer AS-path, likely to increase traffic and revenue of their sister network 3549. Certainly it's common practice to overrule the BGP4 default behaviour, and widely used by smaller networks. Still I'm surprised that it happened obviously rather undetected, at least, to my knowledge, Level3 did implement it silently and hasn't published an official statement or customer announcement, which I think, would have been fair, at least. Considering that Level3 3356 and 3549 are by far the largest networks globally this decision must have a large impact on traffic flows and, of course money flows. Maybe the BGP monitoring experts (aka Renesys et al) can shed some light? -- Fredy Künzler Init7 / AS13030
