Hello,

 

post the full running configuration of your ASA...


My inside network 192.168.1.0

My outside network 10.10.10.0(outside of the firewall) 

asa- in g1/1 

nameif -inside 

   Security -level 100%

 Asa(config)# route outside 10.10.10.2 255.255.255.0 10.10.10.1

Icmp configuration =(access-list oti extended permit icmp any any echo 

=access-list oti extended permit icmp any any echo-reply

=access-list oti extended permit icmp any any unreachable) 

Nat configuration=( object network) # host 192.168.0.0

Asa(Config-network-object) # Nat ( inside,  outside) dynamic interface 

 

 

 

That is my configuration sir 

Hello,

 

--> Asa(config)# route outside 10.10.10.2 255.255.255.0 10.10.10.1

 

Is this a 'real' ASA or a Packet Tracer project ?

Packet tracer project 

Hello,

 

that could explain it, the Packet Tracer ASA has a few quirks. Post the zipped project (.pkt) file...

 

Hello

See attached working PT file -

Hello,

 

I am not sure what file you saved, but the one you sent had a lot of errors (missing and wrong static routes on the routers, the access list on the firewall was not applied, the global policy had no ICMP o=inspection, the NAT had only one non-existing host).

 

Attached the working file.

OK I'm working on it after which I am sending it

Hello please i need a favor would you do that configuration and send it to me as my guide 

Nat. 

Access list 

All the necessary configuration on Cisco firewall to enable outside Network routing please
