WAN IP release

October 27, 2023 14:05

I have a question about releasing the WAN (ISP) IP address. I have the FW Gold+, and it's been working well for me (FiOS 1 gigabit). Recently, my home network is having massive problems (things dropping off, reconnection, etc) - WiFi and Wired.

I've replaced what I thought was a bad switch, but the issue has gotten worse, and now I am going to tear everything down and replace/reconnect one by one. While I don't suspect my Firewalla, I also want to replace it (Orbi RB50) just to see.

FiOS gets annoyed if you try and request a new IP from a new device and haven't released the old one (and I don't want to deal with calling their support).

Will the FW Gold+ release the WAN IP as part of a shutdown? And if not, is there a way I can force a DHCP release?

Thanks!

Try this

Network -> WAN -> DHCP Lease Info -> renew DHCP lease

And this will release the old IP and try to acquire a new one

I have the same question, but I want to release the dhcp lease, not renew it

That will kill your WAN right? if you want to do that, you can just remove the WAN

Yes, and I need to do that because when migrating to a new router (upgrading my Firewalla from Gold Plus to Gold Pro), my ISP (Frontier Fios) will not assign a DHCP address to a new MAC address without the old router first releasing its DHCP lease.

You can just disconnect the old router's ethernet cable and that's a much simpler and cleaner solution right?
