Hi,

What do you mean by allowing only gmail pass through firewall?

What happens with DNS or with any other browsing traffic?

If you want to limit the web-based email solutions to only gmail, you would have to use a next-gen firewall solution like sourcefire and not just a simple L3-4 firewall with limited L7 capabilities.

Thanks,

Octavian
