我们正试图在思科RV180路由器上testing一对一NATconfiguration,思科SMB支持认为下面的这个设置不起作用。 (他们似乎是对的)我知道这与ARP条目有关。
ISP Gateway | | (public IP block) | WAN NAT Router LAN | +----Computers connecting to the internet (192.168.1.*) | WAN NAT Router (this one with the One To One NAT rules) LAN | Computers that run webservers (192.168.2.*), each needing their own (192.168.1.*) IP address on the WAN of their router.
如果我们需要一个实验室testing,这个select被认为是我们应该使用的布局:
LAN NAT Router (for simulation purposes only) WAN | WAN NAT Router (this one with the One To One NAT rules.) LAN | Computers that run webservers (192.168.2.*), each needing their own IP address on the WAN of their router.
那布局不保证工作。
但他们确实说,以下是一个安全的赌注:
ISP Router | | (public IP block) | WAN NAT Router (this one with the One To One NAT rules.) LAN | Computers that run webservers (192.168.2.*), each needing their own (public) IP address on the WAN of their router.
我的问题
请解释什么要求是一对一的NAT设置,以及如何使ARP条目正常工作。
如果您有更多关于如何在一对一NAT情况下保留ARP的信息,那将是最有帮助的。
你的问题如下:
