Greetings
First off, I am not a RouterOS guru, I can do the basics & help myself in the most part but am no guru on RouterOS.
The CAP AC WiFi AP I recently installed is ignoring the DNS settings assigned by my network DHCP server configuration. Tried turning off "allow-remote-requests", adding a DHCP-Relay entry and a few other things but cannot get the CAP to allow the clients to get their DNS config from DHCP.
I am not sure if it is the CAP AC forcing the use of the DNS IP's that are configured on it (/ip dns print -> servers) or if it is stripping the MAC Addresses from the DHCP request. Running tcpdump on my DHCP server, I do not see any of the DHCP requests that come via the CAP AC using the expected MAC address so I suspect that the CAP AC is in fact stripping the MAC Addresses so the DHCP server is assigning the "default" config. I have no idea how to fix this and have not been able to find a solution.
Any assistance getting the CAP AC to honour the network DHCP server config will be greatly appreciated
My local network setup is pretty simple:

Code:
[admin@ap1.home] > /ip dns print servers: 10.1.1.1,208.67.222.123,208.67.220.123 dynamic-servers: use-doh-server: verify-doh-cert: no allow-remote-requests: no max-udp-packet-size: 4096 query-server-timeout: 2s query-total-timeout: 10s max-concurrent-queries: 100 max-concurrent-tcp-sessions: 20 cache-size: 2048KiB cache-max-ttl: 1d cache-used: 27KiB[admin@ap1.home] > /ip dhcp-relay printFlags: X - disabled, I - invalid # NAME INTERFACE DHCP-SERVER LOCAL-ADDRESS 0 dhcp-relay bridge 10.1.1.250 0.0.0.0 [admin@ap1.home] >- Single network IP range managed by a RaspberryPi (DHCP, DNS, etc)
- Old PC as a file server & router backups etc
- HAP AC2 (RBD52G-5HacD2HnD) running RouterOS v6.48.6 (long-term) as my boundary router & firewall to the Fibre internet. Does the Internet NAT & port forwarding.
- CAP AC (RBcAPGi-5acD2nD) running RouterOS v6.49.10 (long-term) acting as an AP to extend the WiFi coverage (currently standalone as this is the only way I could get it working and I still need to figure out CAPSMAN).
- RB433 running RouterOS v6.49.10 (long-term) that I use to learn and test stuff before I break primary devices. I know it is old, it is left over from a defunct community WiFi MAN killed now that we have Fibre readily available.
- for the kids, I use the OpenDNS Family Shield DNS IP's & local DNS server for LAN devices
- for the non-hardcoded DHCP clients, I use the OpenDNS Family Shield DNS IP's
- for work, I use OpenDNS Family Shield DNS IP's, Cloudflare DNS IP's, local DNS & company DNS IP's (VPN issue fix ... I know but it works)
- Laptops & phones have hardcoded IP's via DHCP which I use for QOS rules on the HAP AC2
