NAT on Cisco router to reach a device on a different network
Posted on 2004-08-29
We connect to a customer site via ISDN and Cisco 800 routers, unfortunately we both have the same IP network of 10.0.0.0/24, so we use NAT to enable a telnet connection to their servers.
On the remote router, I have the following configuration to reach two of their servers from our network:
ip nat inside source static 10.0.0.250 192.168.2.19
ip nat inside source static 10.0.0.251 192.168.2.20
Then from our network, we just telnet 192.168.2.19 or .20 to get to their servers.
I want to add..
ip nat inside source static 10.0.100.250 192.168.2.21
ip route 10.0.100.0 255.255.255.0 10.0.0.205
Will this work? Can I use NAT in this way to reach a device on a different network, providing I include a route how to get their?
I assume the 10.0.0.205 router will need a router adding back to the 192.168.2.0 network?
Does this make sense?
