FreeBSD won't support this 'out of the box' - because of the problem that you identified of having multiple NICs all with the same address range assigned to them. There's a project called 'vimage' which adds a separate virtual forwarding table per jail. This might work for you, although all the natd's "outside" interfaces would need to sit on the same interface, and I don't know if it can do that. Otherwise - you can run multiple instances of FreeBSD under a virtual machine environment like Xen or VMware, and bridge all the 'outside' interfaces together onto the same NIC. Also - you may still end up with a separate outside IP per vimage or VM, so maybe then you need another NAT instance to NAT all of those onto a single IP address :-) Regards, Brian. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
