MyWanIp is a Windows 95,98, ME, NT4, 2000 and XP utility that allows you to discover your WAN IP address. Many home and small business users have broadband routers like the Linksys, D-Link, SMC, Netgear, Cisco, Agere and others between their LAN and their Internet connection. When a LAN PC is connected behind one of these routers, most IP Address utilities will only tell you the LAN IP or private IP address. This is not useful to someone trying to connect to your router or your computer from the Internet.

- Omniquad Personal Firewall
- License: Freeware

Omniquad Personal Firewall is a personal security system to protect your computers from unauthorised access over the LAN and / Internet. Personal Firewall is a software application used to protect a single Internet-connected computer from intruders. Personal firewall protection is especially useful for users with "always-on" connections such as DSL or Cable modem. Such connections use a static IP address that makes them especially vulnerable to potential hackers . Often compared to anti-virus applications , personal firewalls work in the background at the device (link layer) level to protect the integrity of the system from malicious computer code by controlling Internet connections to and from a user's computer, filtering inbound and outbound traffic, and alerting the user to attempted intrusions.
