Hello All, I am attempting what is seeming to be an impossible scenario for some unknown reason. What I want to do is setup a web server in a an isolated vlan and on this vlan, the server is handing out IP addresses via dhcp to the clients and setting there gateway to this server. What I want to do is now, how do i make it so no matter what address they try and go to using a browser, they are automatically redirected to the internal web server saying that they do not have access to this network. I have tried with a clean install of Debian and doing 1 single iptables rule of: iptables -t nat -A PREROUTING -s 192.168.0.0/255.255.255.0 -p tcp -m tcp --dport 80 -j DNAT --to-destination 192.168.0.1 Which should redirect all traffic going to port 80 to the internal web server at 192.168.0.1. This isn't working, but on the client I can go to http://192.168.0.1 and get the page saying they have no access. Am i missing something here or should this work? if it should work, can anyone try and help as to why it doesn't?
