Securing a wireless network
Posted on 2004-07-30
Maybe someone can help me with this. I was reading an article on securing a wireless network and one of the stragities it mentioned was to purchase a befsx41 linksys router and place it between your access point and your corporate network. Their reasoning was the router had vpn tunneling capabilities. I took this to mean that I could plug my corporate network on one side of the router, my access point on the other and be able to set up a vpn tunnel between the 5 wireless handheld devices that go through that access point and on to my corporate network. But after talking with Linksys technical support apparently the vpn doesn’t work that way. To be honest after talking with linksys technical support I’m not sure what the vpn portion of the router is suppose to do.
So here is my goal. I have my internal corporate network, will call in corp network and I have 2 wireless access point connected to it in the same building. I have 5 pocket PCs and one laptop that connects to those access points. What I want to do is have another layer of encryption and another method of authentication on top of what wep provides. Hence when I heard of putting a router with vpn tunneling in between my access point and my network the idea sounded just like what I’m looking for.
Does any one have any suggestions? Do I need some kind of vpn gateway instead of a vpn tunnel between my corp network and my wireless handheld devices? Also I was under the impression that I could use the vpn client that was included in the xp and the pocket pcs operating system to authenticate onto a vpn gateway, but after some research it seems that those vpn clients will only authenticate to a windows vpn gateway. I don't have room to attach a big server to each of my access point. I need something compact. Does anyone have any suggestion on how to implement a vpn wireless security solution in an affordable way? If I cannot use the client provided in the xp and pocjet pc’s operating system does anybody have a suggestion of a vpn client for the handheld?
Thanks in advanced
