Hi, allThanks for the replies, I installed Smoothwall a free firewall software on an old desktop, this works like magic, it allows me to block sites that I do not want people to see, ports I dont want people to use, view incoming and outgoing traffic via its web interface and most of all it acts as my DNS server so when one ISP fails I just change the cable for incoming traffic from one ISP to the other at my incoming traffic network port and everything continues as normal.
