As per the attached file.
I would like to use iptables to redirect a service to a web portal for registration/authorisation. The IP addresses will be used to authorise access to the service. The addresses will be on a file. Details as follows:
User tries to access the service on port 53, if authorised (ie if on the attached file in lets say /usr/local/etc/[url removed, login to view]) they are granted unconditional access, if not redirected to a portal eg 220.127.116.11 port 80 (18.104.22.168:80). Everything else happens there including updating the attached file so you dont have to worry about how that happens.
- file will be comma delimited in the following format : username,ipv4 address eg markj,[url removed, login to view] (see attached sample file)
- all requests to a specific port (53) will be 'matched / against the file lets call it a whitelist or iplist. the file shall be dynamically changed without having to restart iptables.
- all 'matching' requests will be allowed access to the service. and once established should stay connected.
- all unmatched requests will be forwarded to a portal.
- iptables should not have to be started with each addition/deletion (use iplist) or equivalent
-- on the portal they can register and set up their IP address to be included (not in scope for this job), the portal is configured to automatically update the 'whitelist'.
-- The customer request is then re-forwarded to through the same whitelist before granting access. this should be added 'on the fly' as customers register. we have another process to manage the listing/delisting.
Please get back to me with a clear detailed plan of action, how long this will take and how much it will cost.
Service will run on Ubuntu server 12.x
