Timeline for My CenturyLink fiber modem is bridged - can I just get rid of it and use my Cisco ASA 5505?

| Mar 4, 2019 at 1:21 | comment | added | SamAndrew81 | I was able to successfully use my pfSense router to bypass the CenturyLink modem. I could not get the ASA 5505 working, but I am fairly certain it was just a config issue on my part (not a shortcoming of the ASA itself). | |

| Mar 1, 2019 at 21:41 | comment | added | SamAndrew81 | @Tim_Stewart, I called and spoke with CenturyLink tech support today. The "technician" (using that term loosely) I spoke with did not know cloning the MAC is obligatory or not. So you see, even if they wanted to help (they don't) actually getting the help is a different matter. | |

This is usually a straight forward kinda thing, most ISPs don't force you to use their equipment. If they implied that at all I would escalate the request to customer retention. | |
| Feb 25, 2019 at 17:47 | comment | added | SamAndrew81 | Thank you, @Tim_Stewart. I'm expecting the least amount of cooperation possible from CenturyLink, so asking them for help will be last resort (their support is horrible). | |
| Feb 25, 2019 at 17:44 | comment | added | Tim_Stewart | Try duplicating the WAN Mac address of the Arris WAN interface to the Cisco ASA WAN interface. (MAC cloning) if that fails, you may have to call them and ask them to release the DHCP binding on their end. | |
| Feb 25, 2019 at 17:41 | comment | added | Tim_Stewart | @grawity, Verizon does the same thing. You usually have the ONT (fiber to Ethernet converter) in the basement or garage. Then have the VZ "Fiber router" which is essentially no different than a regular router minus the moca port which feeds set-top boxes. Most likely they have locked the account to the mac-address of the Arris wan interface. | |

Added make/model of fiber-ethernet handoff (ONT)

| Feb 24, 2019 at 22:44 | comment | added | SamAndrew81 | @grawity The fiber-ethernet media converter is a separate box, yes (Calix 716GE-i R2). The fiber is hardwired into the box and it has an ethernet output jack. The Arris C3000T is a Century Link provided modem/router and it only has ethernet ports on it. | |
| Feb 24, 2019 at 21:02 | comment | added | grawity_u1686 | What exactly is a "fiber modem"? It would make sense if the fiber-to-ethernet converter was built into it, but you list that as a separate item – so what sort of device is the Arris C3000T? What's "fiber" about it" and what's "modem" about it? | |
| Feb 24, 2019 at 20:45 | comment | added | Ramhound | If you want to simplify your network, the Cisco isn't required, but I understand the reason you have it :-) | |
| Feb 24, 2019 at 20:43 | comment | added | SamAndrew81 | Yes, that is correct, CAT6. I see what you mean about router vs modem, yes. I suppose I will have to buy one, but was hopeful after reading that original SU post. | |
| Feb 24, 2019 at 20:42 | comment | added | Ramhound | There is a difference between a router and a gateway modem. I am guessing you are connecting the modem to the device with a CAT5'ish cable? | |
| Feb 24, 2019 at 20:39 | comment | added | SamAndrew81 | Well sure, but it is a router. The original post makes it sound like any router that supports VLAN tagging (which the ASA does) will suffice...? | |
