Cisco asa 5505 won't connect to internet

Hi Folks,

Having a nightmare here with a brand new cisco asa 5505. About 6 hours into trying to get the thing working.

Firstly windows 7 refuses to get to its https://ip/admin web interface, but i solved that by connecting from XP.

So, now I have factory reset it with the IP 10.5.0.1

I've got this simple topology:

Win XP Laptop on dhcp > ASA 5505 > Cable Modem > Internet

Now I run through the startup wizard, all seems obvious so hopefully no need to change much in there.

But I cannot get internet access and in ASDM it says "no ip address" on the outside interface. I think this is the problem I need to solve first ??

I tried setting the MAC address of the outside interface to the address of my old router in asdm, in case the ISP is securing by mac address. that didn;t work.

I wasnt sure which port address translation to use. I tried "no address translation" and also "PAT" with "use the ip address on the outside interface". Neither worked

Please help !!!!

thanks

Also whenever I try to run the startup wizard now it give me this

"This license does not allow configuring more than 2 interfaces with nameif and without a "no forward" command on this interface or on 1 interfacess) with nameif already configured"

Only way out of that is to factory reset every time I want to run startup wizard. This is a really bad experience.

Progress, but still need help:

The outside IP is now showing as the internet facing ip - good news I guess. But clients inside the firewall cannot access the internet still.

Please help if you can. thanks

I can get onto the cable modem from the laptop now, but still no internet access.

Cable modem does of course work fine direct to a pc or through a cisco 501.

The cable modems http interface log says "No Ranging Response received - T3 time out" whatever that means !

thanks

now we have to check that vlan 2 has got its IP address and Also is there any route or gateway via dhcp.

so :
please send your show route results, and also show int vlan2.

Its was half working, sort of.

When I go google.com I get the links across the top but no pictures or search box ! weird. It just hangs there for ages.

Since then its gone back to page cannot be displayed. I wonder if it is the ISP validating mac addresses. I didn't change anything between these states.

Pinging 4.2.2.4 returns no response 0/5

Pinging the modem 192.168.100.1 is fine.

When I do ipconfig/renew on the laptop, it seems to take about 2 minutes after changing any settings before i can get my ip address again

How can I ask my cisco 501 what its web facing mac address is?

Lets get that out of the equation before we go further.

I just changed the topology to this

Laptop > Cisco ASA 5505 > Cheap Dlink Router > Virgin Modem

Now I have full internet access. So there's something about the Cisco ASA 5505 and the Virgin Modem which are incompatible when they are directly connected to each other.

The old architecture:

Laptop > Cisco ASA 5505 > Virgin Modem

still does not work - the asa is given a web facing IP by the virgin modem but internet access is not possible.

If anyone knows of a configuration on the cisco that could fix this, please let me know.. thanks
