How to open port on iptables locked on a specific internal MAC address?
I am currently having a slight problem with our firewall. Basically "transmissions" are locked and all ports locked except for HTTP and HTTPS.
However one developers computer has to have access through the firewall on a specific port (the FTP port, 21).
However I need it so that only this specific computer to be able to get through the Firewall. Therefore I thought of opening a port open only for that computers specific MAC address.
However after some googling I haven't found the right command/rule for this. Can anyone tell me the rule/show me where I can find something like this?.
Thanks in advance. :)
Just to clarify: Everything is locked so I thing I may also have to specifie OUT and IN.
i'm very new to iptables but from the manual:
i believe this will work for you:
The syntax on that is missing the module. It's like:
