hi @ Nebula_Irene
When I look at that location on USG40 or USG60 Devices under DHCP there is no Advance (Extended Options)
If I click Add by Static DHCP Table I can only add ip addresses. Is there another location I am missing?
OMG, you are correct. I forgot to hit the show advanced settings.
Do you know if it's possible to add a url? We have ip phones and would like to add option 66 pointing to a url but did not see a url option in the drop down box.
