Cox will allow you to create a home network and have helpful FAQs on their support page. However, if you do have problems with your connection you may be required to connect your modem directly into a computer since Cox will not support home networks due to the complexities and numerous configurations they can have.

"I think it's pretty safe to point out that the option "enable WAN requests", if your router has that option, makes your router pingable, and thus can be troubleshooted by a Cox tech. It'll simply appear as the primary machine on the network."

Thanks to MetalMorph for that.

Cox does offer up to 2 additional IPs to make it possible to have 3 total. This option can be added to the account by the HSD phone tech reps (tier1). After the IPs are added the modem must be power cycled (power disconnected for approximately 45sec-1min and then plugged back in) for the modem to obtain the setting change (new config file) that allows it to pull multiple IPs from the DHCP server. Once this is done the IP lease should be renewed on each machine to verify it can now obtain a public address.

Cox will not support the network directly or the hardware associated with it (hub/switch etc). To troubleshoot problems that arise with this the modem must be attached directly to all PCs individually. Troubleshooting of the LAN hardware itself is generally left up to the manufacturer of said hardware.

The cost is typically a $9.95 one-time setup fee and $6.95 per month per IP. This price may vary slightly from market to market but can be used as a general guide when determining the best multi-pc solution for your individual situation.

Cox blocks a number of ports and services for security reasons and to ensure consistant service to all of our users.

A complete list of blocked ports and rationale is at: »support1.cox.com/sdccommon/asp/c···579e132a

Quite simply, it is to reduce spambots.

If you are in such a situation that you are away from home, say in college, there are two ways around this:
-Use Cox's webmail
-Specify an alternate SMTP server, that you have access to such as your school's mail server, in your e-mail client.

You will probably prefer to use an e-mail client. The incoming server will not change, but you will need to consult your network administrator on getting details for changing your SMTP server.

For DNS servers you can find the addresses this way:

For Phoenix:

Name: ns1.ph.cox.net
Address: 68.2.16.30

Name: ns2.ph.cox.net
Address: 68.2.16.25

You can also find them fairly easily w/ DOS' NSLOOKUP command following Cox's DNS server naming convention.

e.g. NSLOOKUP ns1.xx.cox.net and NSLOOKUP ns2.xx.cox.net where the "xx" is the local area's two-letter code. (or taken from »Cox HSI Router Abbreviations »What are the Cox Router Abbreviations? )
