Last time I saw this issue was when reviewing a wireguard setup.  IP fragmentation 
 in the client->server was very frequent in the pppoe-wan interface.  I think this is why the old way mostly works.

At that time I fixed it by setting a correct mtu value (16 multiples) on the local openwrt side, and having mss clamp in both directions on the remote side.
