From within the FIrewall I can ping the outside interface on the Firewall as well as the internet. Is there something that I need to do on the Firewall to pass traffic past inside interface to the outside.</P> Mon, 11 Mar 2019 12:19:35 GMT https://community.cisco.com/t5/network-security/unable-to-access-internet-from-the-inside-network/m-p/983010#M940721 bericaleb 2019-03-11T12:19:35Z Re: Unable to Access internet from the inside network. https://community.cisco.com/t5/network-security/unable-to-access-internet-from-the-inside-network/m-p/983011#M940723 <HTML><HEAD></HEAD><BODY><P>Hi,</P><P> I think you need to define NAT from inside to outside, use these commands to do so:</P><P> nat (inside) 1 0 0</P><P> global (outside) 1 interface</P><P></P><P>the 0 0 in the nat command means any, you can also just put the internal network if you have only one inside network , example</P><P></P><P> nat (inside) 1 192.168.1.0 255.255.255.0</P><P></P><P>regards</P></BODY></HTML> Wed, 19 Mar 2008 06:08:12 GMT https://community.cisco.com/t5/network-security/unable-to-access-internet-from-the-inside-network/m-p/983011#M940723 alanajjar 2008-03-19T06:08:12Z Re: Unable to Access internet from the inside network. https://community.cisco.com/t5/network-security/unable-to-access-internet-from-the-inside-network/m-p/983012#M940724 <HTML><HEAD></HEAD><BODY><P>Hi </P><P>I've added that in but it's still not working.

Check you interface security levels and make sure you are going from a higher security level interface to a lower security level interface.</P><P></P><P>2. Check your routing. If you can ping the internet from the firewall, make sure your clients are getting routed to the firewall.</P><P></P><P>3. As mentioned in another reply, make sure you have NAT configured properly.</P><P></P><P>Hope this helps!</P><P></P></BODY></HTML> Tue, 25 Mar 2008 17:57:07 GMT https://community.cisco.com/t5/network-security/unable-to-access-internet-from-the-inside-network/m-p/983016#M940730 derrickc 2008-03-25T17:57:07Z
