Title: Howto Request / Renew IP of WAN Interface DHCP Client
Post by: fulb on March 25, 2021, 01:43:13 pm

Hello,
maybe I am confused but I remember that we had in the past a button to renew/release an IP on the WAN interface, pulled by an DHCP client. I can’t find it anymore. Is there a way to pull a fresh DHCP address for this interface in opnsense without rebooting the complete appliance?

A hint would be very useful for me. I am fighting with my changing IPv6 delegations.

Best regards,
Frank

Interfaces -> Overview -> WAN (Release / Renew) maybe? ;-)

Hi,
I created a screenshot from my menu and attached it. In my case I can't find the buttons and I dn't know why it happens. I need this options to request new IPv6  adress. IPv4 is static.

Using the release mech will not work on IPv6, you need to change the ipv6 duid, then reboot. Beware though, some ISPs will reject the change in duid and you may have to wait 30 minutes or so before it will give you a new lease, try it and see what happens.
