I think u meant RFC1323, right ? The same reason is causing me unable to access www.etinc.com and timeout during smtp session. So, does it mean in general the following are true for 2 FreeBSD boxes: 1) Both boxes have tcp_extension enabled and they should talk happily 2) Both boxes have tcp_extension disabled and they should talk happily 3) One has tcp_extension enabled and one disabled and there is no gurantee of the connection ? I believe etinc.com is using FreeBSD, but I do get this problem before when I have the tcp_extension stuff enabled. > Some hardware doesn't handle, or handles incorrectly the TCP > extensions available.
