I just want to assign my router all six IPs that my ISP has assigned to me so I can set up various static NAT forwardings based on the destination address (yes, I know I can do forwarding by port, but I've got two HTTPS (port 443) servers that I want to set up)
...but when I try this:
ip address 22.214.171.124 255.255.255.248
ip address 126.96.36.199 255.255.255.248 secondary
(ip route 0.0.0.0 0.0.0.0 188.8.131.52 = the ISP gateway)
From out on the Internet, I can PING the ..1.2 address just fine, but when I try to PING the ..1.3 address, I get "Reply from 184.108.40.206: Destination net unreachable"
Is it telling me that I can't put two addresses that are in the same subnet on the same interface? I'm sure I've done this in the past. Obviously the packet is getting through to my router's interface since the primary address is the one who is answering back with the ICMP reply, but I can't figure it out.
