Hello, I'm trying to replace a proprietary firewall appliance from a company that went out of business. I'm hoping to be able to use IPCop to do the job. I've listed a couple of my issues below, so if you are familiar with the workings of IPCop, or have some suggestions about other firewall packages, please feel free to comment. Here's a couple things that I really want IPCop to do: Transparent Authentication with Logging ============================== Authentication that will allow me to view a authenticated user and the IP associated to them. I would like for the proxying to be transparent and not require the clients to have to alter any settings. I would prefer (Open)LDAP, as that's what I have set up and working already. Unfortunately I can't find the LDAP username that the user logged in with in any of the logs (VIA the web GUI). Am I missing something? A captive portal would probably be a good idea. Any recommendations as it doesn't seem to have it built in and I can't find an add-on for it. Multiple DHCP pools ================= Is it possible to have multiple DHCP pools that aren't necessarily sequential and would have different masks? ie. one pool might be: 140.179.238.68 to 140.179.238.127 with mask 255.255.255.192 and another might be: 140.179.238.130 to 140.179.238.254 with mask 255.255.255.128 -- -Montana
