https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=203524 --- Comment #1 from eugen@grosbein.net --- Please read ipfw(8) manual page, section BUGG; this is known and documented problem of ipfw nat: Due to the architecture of libalias(3), ipfw nat is not compatible with the TCP segmentation offloading (TSO). Thus, to reliably nat your net- work traffic, please disable TSO on your NICs using ifconfig(8). This PR should be closed. -- You are receiving this mail because: You are the assignee for the bug.
