Re: Nat

Hi ,

You can do a pat for the required private ips . Only your servers can contact outside using pat . If from outside , if you want to reach the servers , you need to do a one to one nat .

pls find the config based on your requirement

access-list 10 permit host 10.10.10.10

access-list 10 permit host 10.10.10.11

interface lo10

ip address 194.126.20.20 255.255.255.255

ip nat outside

int fa0 --- private lan

ip address 10.10.10.1 255.255.255.0

ip nat inside

ip nat inside source list 10 interface loopback10 overload

Also do a "ip nat outside " on your wan interface .

hope it helps

Re: Nat

You can use SDM for GUI based creation of NAT on Cisco router. Ofcourse if only your Cisco router supports then only. SDM is cool. Everything u can do via GUI based interface. Even u can monitor activities of all interfaces i.e. Serial, Ethernet and blah blah blah.
