Note: This is actually the least ideal solution due to my modem only having 1 LAN port, so I would not be able to use WAN 1, meaning I am forced to route ALL traffic out WAN 2 through Spectrum’s second box. Route traffic on a specified LAN interface on the Netgate 6100 to the WAN 2 interface. Connect Spectrum’s second box to the WAN 2 interface II. Note: I would prefer not to have any devices downlinked on Spectrum’s second box. Connect any devices I want associated with the Static IP to the second box’s LAN. Connect Spectrum’s second box to any LAN interface II. I have thought up of a few options to get around the use of the second box… I would prefer to minimize the area of attack as much as possible, by not downlinking any networking equipment from the second box. I have read spectrum’s privacy policy and do not consent to spying on the local network. Ideally, I would prefer not to have this second box on my network at all, but it is claimed to be necessary according to Spectrum’s tech support. The second box is necessary for telling Spectrum’s WAN to assign the static IP address to my internet connection.
