Hello,
I've tried so many config methods I'm not confused on the issue.
I have a DSL modem from Virgin Media and if I plug my laptop into it it gives me a public IP and I can get on the internet, it is doing some sort of DHCP. Now I have put the outside of the firewall into this port and configured the ASA as best as I can but I can't get on the internet from the inside, can you think of any reason why it isn't working?

Thanks, that makes sense to me know.
Also why did the mac address insertion fix my main issue on the outside interface? (whoops I see you replied to this already)

Before reloading the ASA, have you tried flapping the outside interface (shut, no shut)?

No luck with the "shut" "no shut" I'm afraid. I will proceed with the debug and captures.
When I google Virgin Media and ASAs it seems it can be done, but like you say it could be a version issues too. Will be back later with some more info, thanks guys.

Some ISPs might filter vendors as they only wish for you to connect a PC not a router/firewall or whatever device that will provide access to more than one PC.

Any other option would require troubleshooting and it could be related to layer 2.
