My manager wants me to get a Sharp SL-5500 PDA to connect to our wireless network running on a
Cisco 3000 concentrator using VPN software. The question is this: I have tried to use movian VPN
software that Cisco recommends but have had problems with it for the ipaq. Can you recommend some
companies that have decent VPN software? Secondly I need to find a VPN client software that will
run on the embedded Linux OS. Where can I find such software and can you give me some companies
names that you would recommend?
Standalone IPsec VPN clients for PPC are available from Certicom ( movianVPN) and Funk (AdmitOne). I'm surprised that you're having trouble with movianVPN, because it has been demonstrated to interoperate with the Cisco 3000, runs on the iPAQ, and has a reasonably broad set of security parameters. If you haven't already done so, ask Certicom support to help you work out your problems. AdmitOne is also a pretty fully-featured IPsec VPN client, so give it a try if you haven't already. There are other IPsec VPN clients for PPC that are paired with other vendor gateways (e.g., CheckPoint, V-ONE) and other higher-layer PPC clients (e.g., NetMotion, Symbol). But I think you want a standalone IPsec client to pair with your Cisco VPN concentrator.
I don't have any first-hand experience with the Sharp SL-5500 running embedded Linux, but here
are two VPN software packages that I was able to find for that platform: Freeswan IPsec module and ZeeS/WAN. You may also want to visit this Zaurus FAQ page and
