Hi, i got a bit further and it looks like an MTU-Issue i tested now with my 5.10 bridges,vlan and pppoe first 2 working without problems, pppoe works only if i reduce mtu to e.g. 1480 (pppoe has 1492). i tried with this patch (found as difference between my 5.10 and 5.12 hnat trees), but this does not solve it. https://github.com/frank-w/BPI-R2-4.14/commit/5f7d57280c1982d993d5f4ff0edac310f820f607 (bpf: Drop MTU check when doing TC-BPF redirect to ingress) any idea? i wonder why mtu is a problem here, as with 1500 default i still got internet-connection (over pppoe on main-router too) and due to Pathdiscovery it should fragment. Seems this is not working in 5.10 for flowtable. Without flowtable (disable "flow add" line, disabling "flags offload" is not enough) i have no issues. any idea? regards Frank
