When several computers connected to the internet have been setup to forward spam and sometimes virus?

Looking for an answer to the question: When several computers connected to the internet have been setup to forward spam and sometimes virus? On this page, we have gathered for you the most accurate and comprehensive information that will fully answer the question: When several computers connected to the internet have been setup to forward spam and sometimes virus?

To make sure the port forwarding rule is working correctly, the IP address of the rule should point to the computer, or machine, you want the connection to go to. Some users have put internet IP's in or just the wrong IP all together (Such as putting their computers IP in when they want the IP from their Xbox).

An application-level proxy firewall is most detrimental to network performance because it requires more processing per packet. The packet-filtering firewall provides high performance. Stateful and circuit-level proxy firewalls, while slower than packet-filtering firewalls, offer better performance than application-level firewalls.

The built in Windows firewall can be a pain as well, but normally does not cause the problems that many user installed software firewalls cause. But never the less, make sure the windows firewall allows either the port or program through as well. If the windows firewall is corrupted or broken this will keep port forwarding from working as well.

If you’re still experiencing a bad internet connection after trying the suggestions above, your network card, router or modem may be defective. In this case, get a new router, modem or network card and see if the connection is better.
