@Clive_A Thanks for the quick response. Yup, not there under Settings > Services. Seems a bit odd that the 605 and 7206 have it, but not the 7212. Will have to be patient I guess!

I have the latest version of the ER7212PC firmware (ER7212PC V1_1.1.0 Build 20230803 Official Firmware (Released on Aug 23rd, 2023), but it appears to be missing the newly released DNS Proxy feature?...
