Cisco ASA 5505 and no internet access help

Posted on 2012-03-29

Last Modified: 2012-08-13

We are currently having issues implementing a new Cisco ASA 5505 into our network and are replacing an older Sonicwall. We currently have a SBS 2003 server and a Sonicwall VPN Firewall that houses DHCP (yes, the old IT guy put DHCP on the Sonicwall and not the SBS for some reason).

Anyways, the company manager wants the same setup with the new Cisco ASA as the old Sonicwall for the time being, until we get the new SBS 2011 server running. In other words, they want the Cisco ASA running DHCP, as well as the normal VPN/Firewall setup. I tried configuring it using the ASDM; however am having issues with client computers getting internet access. What's weird is that they are able to get IP's via DHCP and only the SBS server is able to get internet access (due to static IP maybe?) for some reason. Below is the running config and any help via ASDM would be greatly appreciated:

Anything showing in the logs when trying to get to the internet?

Unfortunately I wasn't able to get a copy of the logs before I left work yesterday and will not be back in the office till next week.

Does the running config file look good to you however?  Anything I should possibly change to fix the no internet / traffic outside problem?  I essentially just took the IP information I saw from the Sonicwall and configured it to the Cisco ASA.  I was thinking I might have messed up on the static route  or external gateway config somehow, since it's a different setup than Sonicwall, but not sure.

As far as I can see it looks ok (but I'm still trying to get used to the +8.3 syntax ;)

I took the liberty of adding the "Cisco PIX Firewall" topic to your question to see if we can get some more assistance from my fellow experts.
