I have a Surf SOHO MKIII, latest firmware (8.0.2), and when I turn on Advanced -> Service Forwarding -> “Forward Outgoing DNS Requests to Local DNS Proxy” my DNS responses get truncated to 512 bytes. Moreover, the TC flag is not set on the header so the client doesn’t know the response has been truncated.
- Could we do away with the truncation?
- If not, could we set the proper header flag (TC) in cases of truncation?
