VPN over VSAT
by njungelloyd＠gmail.com 31 Jul '12

31 Jul '12

Hi Guys, I recently deployed the above mentioned. On one end, a VSAT link (512Kbps by iWay) on static IP on a /30 subnet i.e (2 public IPs, one for the modem and the second for a PC running Ubuntu Server/Zentyal eBox Platform running as the LAN "gateway". On the other end a Cisco 1900 series router on a Safaricom 512Kbps dedicated link. My question is, has anyone on the forum implemented an IPSec tunnel over VSAT before? I am very much aware of the expected latency as far as shooting a signal "halfway into space and back" is concerned but any tips or pointers to optimize responsiveness (which is slugish at the moment) of the said tunnel that is exclusively running Remote Desktop Protocol will be highly appreciated. Cheers. ---------- Sent via My Mobile Device

Not sure if your questions relate only to the traffic between the data centre alone, all all traffic including the incoming traffic from customers. For the former, I know only of BGP, but if your data centre can operate independently of each other, there is two ways you can go about this: You can run a BGP session between the two data centre. Its more involving in that you need to have a big IP block so that they can allocate you a AS number, a reliable link between the two data centre and good network know how. You need three ISP, one into data centre 1 , another into data centre 2 and one between them. Its petty resilient though when well implemented in that you likely to survive most network outage, but boy, its expensive and in my opinion hard to maintain if you are a small team The method I would recommend is using some DNS companies that has fail over capabilities. I have used Neustar and they are amazing. No change to your existing infrastructure except you will have to outsource DNS services :( In normal operation, they load balance your traffic between data centres. If you have an outage, they fail over the traffic to the working data centre immediately. You select when the fail over kicks in. By that I mean, they have probes all across the globes. You can for example set it so that fail over take place only when 2 or 3 probes can not reach your systems. This ovoid fail over when upfront ISP have transient issues, like convergence after route change. Unlike BGP, current sessions do die, but you have a far simpler solution. I am assuming you can live with that http://www.neustar.biz/enterprise/dns-services/external-dns-advanced-servic… > > Regards, > > Edwin Ngige William > 254 722 841853 >

SCOM 3G flakiness
by Odhiambo Washington 30 Jul '12

30 Jul '12

Since Saturday, Safaricom 3G has been quite flaky. I wonder if anyone else has seen that. It still persists... So we can safely dump Zuku and Safaricom together as "poor Service Providers". One is perennial, the other occasional. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ I can't hear you -- I'm using the scrambler.
