At work I was the network guru. Had a MAC setup with software to make it a router. It had two network cards. One was public with 2 sets of IPs for our 2 internet providers. The other network card had our private network and our DMZ. The DMZ had our internet servers on it with rules that restricted access based on where you were coming from. It only allowed public access to those devices on specific ports, web, mail, etc. The router also acted as a VPN to our privated network for some services on only a couple of machines. It would gang the surfing between both ISPs so surfing was twice as fast. Also hosted 2 DNS servers on on each ISP. The internet serves also had both ISP IPs pointed to them so if one went down within 10 minutes internet traffic would come inn thru the other based on DNS TTL, Time To Live.

Had some people I know that were hackers try to hack our internet connection and they could not get in. If they tried to hack in it answered in Kligon with "Service not available" and started blocking their IPs.
