I have a RHEL 5 DHCP server that I use to allocate IPs to my users. Only users with MAC addresses registered got IPs in the LAN.
My umbrella organization also provides wireless, they give out IPs that are not on my LAN. I want to implement a VPN server, preferably on the same DHCP server, so that MY users who use the wireless can run a client and have my IPs (and have access to my resources like printing and network storage …)
Any pointer to an open source package that can do that is really apreciated.
