---------- Forwarded message ---------- From: media(a)telecom-media.co.nz <media(a)telecom-media.co.nz> Date: 20-Jun-2005 13:19 Subject: UPDATE – OUTAGE ON TELECOM NETWORK To: imcdnzl(a)gmail.com UPDATE – OUTAGE ON TELECOM NETWORK Telecom technicians have identified the two locations where the North Island Telecom network has today been damaged and are working to repair them. It is anticipated that a patch will be in place by late this afternoon, enabling the restoration of services. A large number of mobile, Internet and other data services have been affected. In addition, many voice calls on fixed lines are congested. The outage has been affecting customers since late this morning. Telecom is working to repair the outage as soon as possible. Telecom regrets the inconvenience to customers and will provide more information throughout the day. The outage, which occurred at 10.48am today, was caused by physical damage to the network on both the east and west coast sections of the network. Technicians are currently working on repairing both the eastern fibre break which is in the Rimutaka area, and the western break in south Taranaki. The outage is affecting calls to Telecom's own call centres, causing overloading. Telecom is asking customers to be patient. We will provide more information as soon as possible.

Help requested - Netscreen IP Sec VPN over DSL
by Felix Tsang 19 Jun '05

19 Jun '05

Can anyone please give me a pointer as to why I am having big problems with using a Safenet VPN client (conecting to) -> Netscreen VPN/FW appliance via Jetstart / UBS / Jetstream ? This is happening on multiple disassociated / unrelated networks. I am using mostly Dynalink RTA300 DSL Modems, and Netscreen 5XT / GT boxes. I believe it is something to do with the NZ DSL network as this type of VPN setup has worked well for over 1/2 years until it start to become more and more unreliable. Can anyone help or suggest a solution? Thanks for your time. Cheers Felix Tsang ULTRATECH Ltd Cell Phone: (64) 29 241 0185 Phone: (64 9) 309 8393 Fax: (64 9) 309 8393 Email: felix(a)ultratech.co.nz

Thanks Tracy, Yes the MTU size could very well be the issue. Just as of Friday, the VPN's came up again through no apprent reason. I have confirmed thru trial that the max MTU size I can put thru the DSL link is 1418 bytes. I'll just have to wait till the VPN's drop again to do the MTU test. Hopefully it'll point to something.

(http://www.qorbit.net/nn/Dec-2002/0254.html gives some details). We had the problem where a client could access their LAN ok via a dialup connection, but as soon as they started using mobile jetstream, things just broke. If I remember correctly set flow tcp-mss or set flow tcp-mss 1300 was the fix. The client has a Netscreen 5 with a Speed Touch Pro ADSL router, then is using Netscreen remote as the VPN client (Rebadged Safenet VPN client). -Tracy B

I wear the other hat (use hardware VPN). We run large numbers of VPNs over DSL (Telecom and TelstraClear) and don't experience any issues. It wont be the hardware used in the Exchanges (baring a hardware issue, such as a bad port). Assuming your ISP is not running out of bandwidth, it wont be your ISP. Your first guess, the DSL router at the CPE end is the most likely culprit. If your using UDP encapsulation you may find it is deleting the NAT translations. If you have an option to turn on ISAKMP keep alives, try that. -----Original Message----- > Can anyone please give me a pointer as to why I am having big problems > with using a Safenet VPN client (conecting to) -> Netscreen VPN/FW appliance via > Jetstart / UBS / Jetstream ?

I used to be Netscreen support for Renaissance NZ and while I saw a few strange issues I never saw a problem with IPSEC VPNs specifically over ADSL. Without knowing where the device in question was sourced from, I can't be totally specific, but assuming it was purchased through a NZ retailer / SI / Supplier, You should get in touch with them - and if you have no luck, phone Lan1 or Renaissance. Remember that the suppliers generally only provide support to resellers, but they both have some talented people that might help you out - I know both have operated some form of professional services department at some point. I'd echo Steve's general thoughts that it's more likely to be a router issue than an ADSL issue (unless you're trying to do something over PON or whatever Telecom call that now). Best of luck. N.

Can anyone help or suggest a solution? I've recently been doing some research trying to isolate a problem with a clients multiple Linux-based IPSec VPNs running through consumer-grade ADSL routers. (I would guess that your Safenet/Netscreen devices are using some form of IPSec VPN). My findings were unusual; the more recent the model of ADSL router used, the more unreliable the VPNs became when under load. For me, this was only the case when running multiple VPNs. Older model ADSL routers performed admirably (the Nokia M1122 was fantastic) while later model ADSL routers ranged from some models reliably crashing after 30 seconds of load to other models seeming ok on the bench but performing very badly in the field. Some brands actually got worse with more recent firmware upgrades or chipsets. Some googling revealed that there may be problems routing ESP traffic for multiple IPSec VPNs through cheaper, less well engineered ADSL routers. I am guessing that modern consumer grade ADSL routers fall into the "less well engineered than they used to be" category. Its just barely possible that this also applies to the hardware used in the exchanges and ISPs. Just a guess. For what its worth, we are moving away from IPSec to openvpn. Unfortunately, once you've bought into a hardware VPN solution, it becomes somewhat harder to make that sort of change... _______________________________________________ NZNOG mailing list NZNOG(a)list.waikato.ac.nz http://list.waikato.ac.nz/mailman/listinfo/nznog NOTICE: This message contains privileged and confidential information intended only for the use of the addressee named above.
