All pages just eventually time out I just can't seem to work out what the issue is!!!
Any assistance would be greatly appreciated
Copied below is the config I am currently using

Hi Robert,
Few things zou need to let us know:
++ Is your Outside IP address issued by DHCP?
++ Does this connection also provide you with DNS resolution?
I have noticed your default route outside is set as: "route outside 0.0.0.0 0.0.0.0 192.168.1.254 1" Which is the Internal IP address of your Firewall to the LAN. This should be set to your ISP's DF Gateway address or if its your lan, your next hop...

You must remove this entry so that DHCP will learn the default route

Thanks for responding I am going to try out what Irmoore suggest which makes sense.
You don't know how long this has been driving me mad!!!
Message for Chouckham yes my outside address is issued by DHCP. Vlan 2 is plugged into a cable modem which doesn't have a fixed IP address. And that DHCP address does get DNS resolution.
I did also notice that I wasn't able to get an IP address from connecting switch port 0 directly into the cable modem. After quite a bit of fault finding I discovered the issue to be with Cisco using a very long Vlan2
Ethernet 0/0
Client-ID: cisco-1cdf.0f5c.61e7-outsi
I managed to get round this by setting up client id to use a MAC address the cable modem was use to speaking to.
This however never got me to a place to open web pages.
I am hoping by removing this entry it will
I will post back nad let you know if its a winner!!!

Exactly as both Irmoore and I pointed out the "route outside 0.0.0.0 0.0.0.0 192.168.1.254 1" is incorrect and should be removed.
Please let us know the outcome.

Hi guys basically what you both suggested was correct so how do you want me to award the points.
I have to admit the user Chouckham suggestion was clearer in that he told me exactly what to do so would it be fair to split the points????

I found an issue or “bug” in the SonicOS platform (the firmware controlling SonicWALL security appliances) that has to do with renaming Default Service Objects, which then causes a portion of the system to become uncontrollable and unstable.
