We have a dedicated Server, around 4 websites, all Zencarts.
We would like to install IP Ban for few countries.
When visitors from that country visit us, they will see
1) Our URL on top
2) Under Maintenance page.
Can also show you example for the same.
We can add some exception IP's for the same country so that they can view the website.
Programmers already done such kind of job will be preferred.
Message me with the best way you can do it, also message if we need to buy some services which will provide IP address and update them regularly.
