Hi! I was able to setup my wireless network on a blue interface on IPCop. What I did was turned off the DHCP on the Linksys router and allowed the IPcop box to provide IP addresses for wireless users. I also turned off the WEP Encryption on the router and for the wireless users to connect to the network, they will have to inform me so that I can add them up to the "blue acccess" on IPCop. Now my question is this. Is it really unsecure to disable WEP encryption on my Linksys router? I notice that eventhough the wireless users have IP address given by IPCop, they still won't be able to connect to the internet or access other networks such as green. They will only gain access if I put there MAC addresses on the "blue access" on IPCop. Is this too much vulnerable? If I have my WEP turned off, what are the chances that the wireless users will be able to connect to the green network? I don't know how IPCop handles blocking proxy port of the wireless users unless listed on the blue access. But it makes sense to me. Even if you were able to connect to the router, you can't do anything right? Now, can someone tell me if there are some security issues on what I did. If so, what are my options to harden the wireless security and secure my Green network? Is OpenVPN secure enough cause I also installed OpenVPN addon on IPCop to enable me to connect to our network even when I'm away. Do I have to worry more on my current setup? I just wish I can also have have an addon for IPCop to enable me to provide access levels to users, time-constraints and better authentication..
no blue users will not be able to access green unless you put pinholes in the firewall allowing blue to access green. blue will be able to access red if they spoof an accepted MAC address, but other then that they will not have much access to anything.
i do not know much about openVPN to answere any security questions about that sorry.
from what i understand about IPCop is this:
RED = outside world, or other firewall
GREEN = inside and secured, behind firewall, network with its own IP scheme on a private network.
BLUE = wifi (can be used for other, but built for wifi) blue is also behind the firewall and secured that way and is also on its own IP scheme on a private network. not the same as GREEN and can not see GREEN.
ORANGE = DMZ
so even if they pull an IP address unless they can find a MAC address that works with IPCop accept list they will not have access to the internet and unless you disabled some of the firewall they will not have access to GREEN.
