Ordinarily, I would expect that since the MTU setting is in the ifconfig_em0 configuration line, this was sufficient. However, I realize now that this is not the case. Putting the MTU into the ipv6_ifconfig line did the trick. This is a rather serious violation of POLA --- I would suggest that some thought should be given to how this is configured and documented. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
