In the 15.0-RELEASE variant (which the network configuration is from) I also manually changed that, but given it lacks the txcsum patches there was no change. I'll try to test on this configuration with those txcsum patches to= o. If the jail's bridge turns of txsum then somehow that does not seem to propagate via the epair to the host's bridge however. --=20 You are receiving this mail because: You are on the CC list for the bug.=
