new switch cannot access internet, routing issue: 5412zl

Hey gang,

 

I have an issue that I found users had close to the same problem but their fixes were not mine.  We upgraded from a 5308XL to a 5412zl recently.  I manually created on the VLANS on the device and everything internal seems to work great.  I cannot however accesss the internet.  I can manage the firewall via IP and the firewall can talk in/out fine but my new switch cannot talk outside of our network.

 

I will link my two configs in hopes that someone can point out my ignorance in getting this set up.  From behind the new switch if I try to ping anything outside the firewall (dns server) it defaults back to 192.168.1.1 Detestination unreachable.  Combine with my firewall packet monitor never seeing any data for the IP i'm pinging -t with... tells me it's a routing issue.

 

Any help would be greatly appreciated!  And in the honor of the person who guides me to a resolution I shall build a web shrine to honor you (ok really i'll just kick a shout out on facebook and give a kudos in here).
