simultaneously different WAN IPs break apache2 but not internet
by mrmazda from LinuxQuestions.org on (#5ESAY)
Several months ago, my small time cable provider was purchased by a larger provider. Two months later, my website on Apache2 broke for internet access (but not for LAN), while everything else about internet remained and remains working normally.
I found that my provider, https://whatismyipaddress.com/ and speedtest-cli all report my IP address as 24.50.w.x (which has changed #x only 2 times in intervening months, much more often than the 6-24 months I've experienced over the past two decades with Spectrum and its predecessors).
However since the web site break, the web page for setting up my router has reported a very different WAN address (obtained via DHCP): 100.73.y.z. I've discussed the problem with various employees for tech support of my provider, none of whom have explained what is happening. One tech suggested I needed to commit to paying an extra monthly fee to lock down my WAN IP. Another said something about some kind of bridging required on their part needed to be done, but doing it didn't change anything.
I fail to see how either of these things could explain the difference between my router's report and the others. Several router reboots haven't helped. Switching modems hasn't helped.
What could be going on? How can I get the different WAN IPs reconciled so my web site can be running again?
(I'm using one of my two own cable modems to save the $9.99USD monthly rent charged.)
