We are having problems with our firewall. It was working this morning and then recently just quit. Everything works great except for internet access. We have a site to site VPN that works. We are able to email outside the network and receive email from outside the network. The live log on the firewall is constantly getting a deny by the access group External_asccess_out.

I can't seem to find where that is or how to change it. Outside the firewall everything works

My running config is below:

also your problem ACL appears to be doing nothing other than allowing Telnet outbound? remove it
no access-list external_access_out_V1 extended permit tcp any any eq telnet  
no access-list External_access_out extended permit tcp any any inactive
no access-group External_access_out out interface External

then to allow Telnet ouybounf add the following
access-list Internal_access_out extended permit tcp any any eq telnet

Internal_access_out is the group causing the denial now.

- Nice one
If you needed UDP out then it was probably DNS and NOT web traffic that failed :)
