All my interfaces are jumbo-capable. I have a dmz (nothing on it right now apart from my NATting router) and an edgerouter lite 3 device running OpenBSD 6.8 and pppoe. On the pppoe config I have MTU 1500. On the ethernet I have MTU 1520. If I were to set the ethernet interface equal or less than the pppoe interface, then I can't access some sites and these include all the common search engines. No mss clamping is set in pf.conf. I don't know the technical why, though.
