The problem is that every encrypted packet transmitted is truncated - tcpdump shows something like the following: 11:15:12.895052 truncated-ip - 120 bytes missing! 213.38.150.1 > 194.73.188.40: ip-proto-57 184 (ttl 255, id 54) If I use an Intel Etherexpress 10/100 card (fxp device), everything works fine. On examining the Realtek driver if_rl.c, the reason would appear to be because it only takes the first mbuf from the chain and ignores the rest when constructing the frame to transmit, while the fxp and other drivers appear to deal with mbuf fragments correctly. Is this the correct diagnosis or am I way off track? Is there any solution to this problem? (other than not using a Realtek card for this purpose) Regards, David -- Dr David Hedley, Head of Development Intelligent Network Technology Ltd, Bristol, UK http://www.inty.net/ This email has been virus scanned using Sophos Anti-Virus by intY (www.inty.net) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
