ARIN-2011-1: ARIN Inter-RIR Transfers - Last Call (expires in one week)
by John Curran 11 Nov '11

11 Nov '11

NANOG Community - There is an Draft Policy for Inter-RIR Transfers presently in extended "Last Call" in the ARIN Policy Development Process. The Last Call will run for one more week, and allows an opportunity for anyone in the Internet community to provide feedback regarding this proposed number resource policy. Feedback, including statements in support or opposition, may be sent to the ARIN Public Policy Mailing List "arin-ppml(a)arin.net<mailto:arin-ppml@arin.net>" (http://lists.arin.net/mailman/listinfo/arin-ppml to join or view archives) A copy of the Last Call announcement, including the most recent changes and draft policy text, is attached to this email. Feel free to forward this email to anyone in the Internet community that you feel may wish to comment in support or opposition to this draft policy. Thanks! /John John Curran President and CEO ARIN Begin forwarded message: From: ARIN <info(a)arin.net<mailto:info@arin.net>> Subject: [arin-ppml] ARIN-2011-1: ARIN Inter-RIR Transfers - Last Call Date: October 19, 2011 3:11:59 PM EDT To: arin-ppml(a)arin.net<mailto:arin-ppml@arin.net> The ARIN Advisory Council (AC) met on 14 October 2011 and decided to send an amended version of the following draft policy to an extended last call: ARIN-2011-1: ARIN Inter-RIR Transfers The AC provided the following statement: ******** The Advisory Council reviewed the results of feedback from the ARIN XXVIII Public Policy Meeting concerning Draft Policy 2011-1 Inter-RIR Transfers. While there were concerns regarding the presented wording, there was significant continued support for a policy enabling Inter-Regional transfers of IPv4 number resources from organizations able to make them available to any organization with valid requirements. In addition to cumbersome wording, the presented text could not be cleanly inserted into the NRPM. The following is new language that directly modifies section 8.3 "Transfers to Specified Recipients" to allow such transfers to or from organizations in other regions. The first paragraph is a modified version of the current 8.3 policy language, envisioning resources being released to ARIN by the authorized resources holder or additionally by another RIR to be transferred to a specified recipient. The second sentence was reorganized to emphasize that it applies to an organization within the ARIN region that will receive such a specified transfer, and to eliminate the single aggregate language per 2011-10 which is also being sent to last call. The new second paragraph adds language enabling transfers to a specified recipient in another RIR's service region. This language specifies that such recipients justify their need to their RIR, following that RIR's policies. ARIN will verify that there is a compatible needs based policy that the other RIR will use to evaluate the need of the recipient and that both RIR's agree to the transfer. Implicit in the intent of the language presented and in conformance with statements made, the size of the block to be transferred is identified as /24 or larger, for obvious practical reasons. In accordance with concern for immediate adoption, the AC chose to forward this version to last call. Concerns expressed by some stakeholders for further controls were noted by the AC, and are being considered for future policy modification, assuaged in part by ARIN staff assurances that if any significant abuse of this policy were to occur, then the policy could easily be suspended. The AC thanks everyone in the community for their help in crafting this important policy and for your statements of support or other comments during Last Call. ******** Feedback is encouraged during the last call period. All comments should be provided to the Public Policy Mailing List. Last call for 2011-1 will expire on 16 November 2011. After last call the AC will conduct their last call review. The draft policy text is below and available at: https://www.arin.net/policy/proposals/ The ARIN Policy Development Process is available at: https://www.arin.net/policy/pdp.html Regards, Communications and Member Services American Registry for Internet Numbers (ARIN) ## * ## Draft Policy ARIN-2011-1 ARIN Inter-RIR Transfers Date/version: 14 October 2011 Policy statement: 8.3 Transfers to Specified Recipients In addition to transfers under section 8.2, IPv4 number resources may be released to ARIN by the authorized resource holder or another RIR, in whole or in part, for transfer to another specified organizational recipient. Organizations in the ARIN region may receive transferred number resources under RSA if they can demonstrate the need for such resources in the amount which they can justify under current ARIN policies. IPv4 address resources may be transferred to organizations in another RIR's service region if they demonstrate need to their region's RIR, according to that RIR's policies. Inter-regional transfers may take place only via RIRs who agree to the transfer and share compatible, needs-based policies. Such resources must be transferred in blocks of /24 or larger and will become part of the resource holdings of the recipient RIR.

Firewalls - Ease of Use and Maintenance?
by Jones, Barry 11 Nov '11

11 Nov '11

Hello all. I am potentially looking at firewall products and wanted suggestions as to the easiest firewalls to install, configure and maintain? I have a few small networks ( 50 nodes at one site, 50 odd at another, and maybe 20 at another. I have worked with Cisco Pix, ASA, Netscreen, and Checkpoint (Nokia), and each have strong and not as strong features for ease of use. Like everyone, I'm resource challenged and need an easy solution to stand up and operate. Feel free to ping me offline - and thank you for the assistance. ---------------------------------------- Barry Jones - CISSP GSNA Project Manager II Sempra Energy Utilities (760) 271-6822 P please don't print this e-mail unless you really need to. ----------------------------------------

Encrypted RPC and firewalling
by Lasse Birnbaum Jensen 10 Nov '11

10 Nov '11

hi all I would like to know how you guys handle encypted rpc across firewalls. We utilize an ASA platform and the DCERPC inspection cant handle encrypted RPC (which is standard in most windows 2008 and default in all communication in exchange 2010). Ciscos says: disable encryption or create "allow any" rules. Do you limit the RPC port range on the windows systems and make "holes" in the firewall for these or do you disable RPC encryption ? Please share your knowledge in this area. Best regards Lasse Birnbaum Jensen Network administrator, IT-Service University of Southern Denmark Email: lasse(a)sdu.dk

Anyone seen this kind of problem? SIP traffic not getting to destination but traceroute does
by Jay Nakamura 10 Nov '11

10 Nov '11

We ran into a strange situation yesterday that I am still trying to figure out. We have many VoIP customers but yesterday suddenly select few of them couldn't reach the SIP provider's network from our network. I could traceroute to the SIP providers server from the affected clients' IP just fine. I confirmed that the SIP traffic was leaving our network out the interface to the upstream provider and the SIP provider says they couldn't see the SIP traffic come into their border router. SIP traffic coming from SIP provider to the affected customer came through fine. It's just Us -> SIP server was a problem. I thought there may be some strange BGP issue going on but we had other customers within the same /24 as the affected customers and they were connecting fine. The traffic at the time traversed Our network -> Qwest/century link -> Level 3 -> SIP provider I changed the routing around so it would go through our other upstream, AT&T, and it started working. With AT&T, the route was Our network -> AT&T -> Level 3 -> SIP provider So my questions is, is it possible there is some kind of filter at Qwest or Level 3 that is dropping traffic only for udp 5060 for select few IPs? That's the only explanation I can come up with other than the whole Juniper BGP issue 2 days ago left something in between in a strange state? I read the post about XO doing filtering on transit traffic, I haven't seen anyone say Level 3 or Qwest is doing the same.

Performance Issues - PTR Records
by Matt Chung 09 Nov '11

09 Nov '11

I work for a regional ISP and very recently there has been an influx of calls reporting "slowness" when accessing certain websites (i.e google.com/voice/b) via HTTP. After performing a tcpdump and analyzing the session, I have been able to pinpoint the latency at the application layer. After the tcp session has been established, it takes up to 15-20 seconds before the application begins sending data. The root of the problem was that the PTR record for our customer(s) address does not exist. As soon as the record is created, latency from the application is eliminated. This is analogous to latency when accessing a server over SSH when no PTR is available. A seperate packet capture from another customer exhibiting similar performance behavior showed many TCP retransmissions. At first glance, I assumed this was network related however this correlates with the application not responding and inducing retransmissions at the TCP layer (different symptoms, same problem). Historically, there was no compelling reason to create PTR records for our CPE however more and more applications seem to be dependent on it. Although we will be assigning a record for each address, my question is why is the application (specifically HTTP) dependent on a reverse record ? What is the purpose? Hope this is helpful as well -- -Matt Chung
