[CentOS] web filtering for remote computers

Hi,

I am using Squid for local users since two years & is working fine.
I am trying to implement web filtering for remote computers e.g few laptops & branch / franchise computers on dynamic ips.

I do not want to use Squid proxy for it, if all remote computers will use Squid from my public ip, bandwidth utilization will increase.
Need valuable suggestion to achieve this.
