I have 2 Virtual Lans and 1 WAN interface active on my cisco 1812 router/firewall.
Vlan 1 (eth2) = 192.168.100.*
Vlan 2 (eth3) = 192.168.200.*
Wan (eth0) = IP Adresses available from my ISP 212.265.208.48 - 212.265.208.62
My Router has the following IP addresses assigned:
Vlan 1: 192.168.100.1
Vlan 2: 192.168.200.1
Vlan 2 is configured as a DMZ on the IOS firewall.
Now what I can't seem te get working is to get Outside to Inside NAT.
I have a webserver IP 192.168.200.3 on my vlan 2 (DMZ) wich I want to be accessable from the internet on public IP 212.265.208.51.
So I set the following command (I usually do it with the Cisco SDM GUI but this maybe more clear to you):
ip nat outside source static network 212.265.208.51 192.168.200.3 255.255.255.255
But this results in:
B. Windows 2003 tells me there is a IP address conflict.
C. My webserver is still not accessable from the internet.
Does anybody know how to fix this??
