一.本系统目前网络现状
服务器单独在vlan1, 4006配置了三层路由, vlan1地址10.10.10.249,所有VLAN通过PIX515做NAT 上网。 PIX 内部地址:10.10.10.1,服务器的网关均指向10.10.10.249。
4006三层配置(部分):
start--------------
interface Port-channel1.1
encapsulation dot1Q 2
ip address 10.10.10.249 255.255.255.0

PIX的outsie接联通的网络.
二、网络需求
因为联通网络不能提供足够的IP地址做所有服务器的发布.所以本单位决定再租用电信的一条链路来发布其他网站.如图所示.
请问这个系统应该怎么规划?
