Hi all,
Feel really silly with this, I'm sure I've followed so many guides, and literally stuck with the default configuration (factory resetting numerous times!) but still can't connect out.
I've been given a LAN IP Range, with /29 address. I've been told that x.x.x.16 is network address, .17 is router address & default gateway, .18-.22 useable.
If I connect a network cable straight to the router they supply, and do manual IP config (as DHCP etc is disabled) with those values and their DNS servers, I can access the net fine.
As soon as I connect ASA 5505 the troubles begin!
My private network IP range is 192.168.128.1-255. I've set the Cisco ASA 5505 to 192.168.128.9, and got a DHCP server up and running, assigning IPs etc (from .50 upwards). The DNS i've tried setting but none of the IPs given by my ISP will resolve, presumably due to firewall connectivity issues. For default gateway I've tried my public IP as given by ISP x.x.x.17, and I've also tried 192.168.128.9 as suggested on some other sites (I believe this to be the correct config now too, but it still won't work)
I can ping 192.168.128.9, but can't ping anything on the internet. Trying to connect to site just gives me DNS errors and 'resolving host' or waiting for host etc.
I've also got the following line in my logs - but not sure why as I wasn't trying to connect to google or use their DNS!

dst outside:8.8.4.4/53 by access-group "inside_access_in" [0x0, 0x0]
What's this "inside_access_in"?! I only have inside and outside. I've tried to access IPs from ASDM troubleshooter, but I get blocked by rule - there is an implicit Deny rule, but I haven't set up any deny rules - I've put some allow outs (as in guides I've seen). Ahhh help!?!?! :)
Here is the config - haven't done very much at all as I literally want to get on the internet and save it, then care about the rest! This is my first cisco config so I want to learn... but it's also becoming mission critical that the new internet is up ASAP.
