3com Open Port Guides

3com, a computer networking company, was founded in 1978. 3com has since been acquired by Hewlett-Packard in 2010 for approximately 2.7 billion dollars.

Here is our list of port forwarding guides for the 3com routers. All you need to do is select your model number from our list. If you don't see your exact model number, we recommend finding one that seems similar. Most 3com routers use a similar interface, so a different guide may work great for you.
