Several Network Related questions(VPN and Firewall)
Alright. First off thanks for taking time to read my post. I am running Mandriva 2005 LE(10.2), on an Athlon 2400+ with wireless as internet, and I was thinking about implementing servers for intranet use, as well as VPN. I am using VSFTPD for FTP and Apache 1.3.3 for HTTP. I have no idea how to do certain things like only allow a certain range of IP addresses to use protcols without restrictions (I need the IPs of the VPN connected computers and the computers on the network to have unrestricted acess to FTP and HTTP as well perhaps SMB and NFS.) on the firewall that comes with Mandriva. If someone can point me in the way of a good firewall, or how to fix the firewall that comes with Mandriva that would be nice.
The next issue is slightly more complicated. I am forced to do several things the hard way, because of restrictions in my ISP's (InsightBB) EULA. I can not do 'dedicated hosting' on my connection so I was thinking of VPN. I have a D-Link router that has several computers connect to it and masks them under one MAC address, so it only gets one IP. I need a VPN server that will allow several of my friends (also on InsightBB), to connect to my computer via VPN to my linux machine and access my wireless network, as well as servers on my linux machine. Are there any servers that will do this easily? Is there a special way this should be done with this kind of router? Should I set my linux server in the router 'DMZ'? Also all the clients will probably be windows based machines so If someone could point me in the way of a good SSL/TLS client for win32 it would be much appreciated(builtin win vpn client runs PPTP). All comments appreciated.
