You can only limit what you send and in this case that works in your favor. On the internal interface, the destination of your packets is the 'real' internal address, which you can shape on. If you want to limit *outgoing* traffic, from your internal segment to the internet, you need to 'mark' your packets when they come into your system, and then shape on the mark when they go out. This is possible. Regards, bert -- http://www.PowerDNS.com Versatile DNS Software & Services Trilab The Technology People Netherlabs BV / Rent-a-Nerd.nl - Nerd Available - 'SYN! .. SYN|ACK! ..
