Hello My Dears,
I want configure my 3845Router to act as NAT server to connect local user to the Internet & Internet users connect to my web server.
For 1 step want access local users connect to the Internet , config 1st interface to 3 sub-interface and config the Switch port that this port connected to as a Trunk port.
At the end config a client follow this :
1- set IP address & Net mask
2- Set the "Default Gateway" as : 172.20.1.1
3- Set the "DNS" as 22.214.171.124
After this when using the "nslookup" can't connect to the DNS Server.
some line of "sho run" output are attached.
Routing has not been configured on the Swicth.As I said do a default route pointing towards the internet link (I hope it is Gig 0/10 .I would like to know the Switch port Gig 0/1 is connected to which device(could be an internet router).ANd the IP address configured on the outside interface is a Private IP address (on Gig 0/10).
If it possible pls share the internet router configuration and the network topology as well.
