    Default Cisco NAT cannot configure.

    Hello, i want to configure NAT static on my router so it can send data to other router.

    I will try to explain everything here.
    So i have 2 PC's hooked up to a switch, which is connected to a router1. PC1 IP: 195.10.5.9 PC2 IP: 195.10.5.10 (both masks 255.255.255.12
    My router1 eth0/0 is 195.10.5.1 with a 255.255.255.0 mask. router1 is connected to another switch via eth4/1 port and this switch is connected to a router2 which is connected to router3 via s2/0 170.100.5.2 and 255.255.255.252 mask, but router3 is not useable its just connected as external network.

    I haven't set eth4/1 or router2 eth0/0 ip's cause i dont really know what ip's to use..

    If anyone can help me i'd be really grateful.

    Regarding IP addressing, NAT is primarily used to convert private IP addresses to a public IP address so you would not use a 195.x.x.x address for a host when using NAT. Try using address from the range 10.0.0.0, 172.16.0.0, 192.168.0.0 range.
