Someone else recently reported similar on their FreeBSD box, and the fix for them was to disable RFC1323 TCP window scaling. Try this: sysctl -w net.inet.tcp.rfc1323=0 If this works for you, you can place the variable=value portion in /etc/sysctl.conf for application upon start-up. If your FreeBSD box acts as a gateway for the rest of your office, and the then that might explain why others are seeing the same thing. Otherwise the problem is likely not FreeBSD-related, and you should talk to your office networking folks to find out what's going on. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
