New ASA 5505 help. 1

[scott0011]

Hi, my company recently purchased a new ASA 5505 to replace our ancient SOHO3. I went through the setup and change the internal ip on vlan1 (inside) to match our internal LAN, and defined the external ip on vlan 2 (outside) to our static ip assigned by our ISP. I also defined the DNS servers for our ISP in the Configuration section of the ASDM. I put the ASA 5505 in place and I can access the internal stuff fine but have no outside access and of course I get the error about unable to locate egress interface. I have poured over the pdfs provided but am apparently missing an obvious step or something. Any help would be appreciated.

Can you post a config? (mask the middle 2 octets of the public IPs and mask the passwords)

I need to see but you probably don't have the default gateway set.

your route outside is wrong
should be
route outside 0 0 gateway_ip

it will fill in the extra 0s
