unfortunately, i do think that the hw checksum is the problem with ipfw+natd -- i have heard similar reports in the past and all disappeared when hw checksum was disabled. Besides, the natd code is old and probably it has not been updated to handle hardware offloadings, jumbo buffers and so on. cheers luigi > # ifconfig ue0 > ue0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 > options=8000b<RXCSUM,TXCSUM,VLAN_MTU,LINKSTATE> > ether 00:60:6e:42:5b:53 > inet6 fe80::260:6eff:fe42:5b53%ue0 prefixlen 64 scopeid 0x7 > inet 172.17.2.111 netmask 0xffffff00 broadcast 172.17.2.255 > nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL> > media: Ethernet autoselect (100baseTX <full-duplex>) > status: active > > Any suggestions or pointers? > > Kind regards, > > Spil. > _______________________________________________ > freebsd-ipfw@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-ipfw > To unsubscribe, send any mail to "freebsd-ipfw-unsubscr...@freebsd.org" _______________________________________________ freebsd-ipfw@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ipfw To unsubscribe, send any mail to "freebsd-ipfw-unsubscr...@freebsd.org"
