I have configured and integrated an ASA to my network.
Inside----ASA----ROUTER-----Internet
I have 3 servers in my inside network,one of them is a proxy server which all other users use. The 3 servers have both public and private addresses.I have done two layers of nat,one on the ASA and the other on the router.
My inside users cannot ping the inside interface of the router neither can they browse.
I have attached the configs on the ASA and router.
Can someone please take a look at it and let me know where I got it wrong.

Can you post a more complete asa sanatized config to get a better picture and see the nonat acls. You said that your inside users cannot get to the inside interface of the router facing asa outside interface and browse, if this is so you simply need a nat statement.
e.i
your asa already have this statement
global (outside) 1 interface
do you have these ?
nat (inside) 1 0 0
or
nat (inside ) 1

Hi,
Make sure you are not filtering out that traffic on the router by the use of access control lists ..?
I hope it helps .. please rate helpful posts

Hi
You can make the configuration as simple,by controlling all the nat operation at the firewall and allow only routing in the router.It will make as simple the configuration.
