Cisco ASA 5505

[Tarqy]

Does anyone have any experience with this kit, I've had one dumped on me at work and I can't for the life of me get internet access via it.

I've got it hooked up to a bridged ADSL modem using PPPoE. Config is below, any help would be appreciated.

I've only got CCNA experience so no experience with ASA or PIX hardware so the syntax may be different, but I don't see any default route in the config so it won't know how to reach any network not directly connected.

http://www.cisco.com/en/US/products/ps6120/products_configuration_example09186a0080ab7ce9.shtml might help a bit. It seems to suggest that you should not enable dhcp on the outside interface if using pppoe. Oh and it will be worth dropping the MTU on your outside interface, try 1462.
Oh and if that is the complete config, you haven't added the inside vlan to any of the physical ports on the device.

Another quick question, are you even getting connected via ppoe ?

Yes the PPPoE connection appears to be working, I can see the interface Ethernet 0/0 has picked up our static IP address from the ISP. As far as I was aware DHCP wasn't enabled on the outside interface as this was not an option when going through the setup.

I also thought that ports 1-7 were on vlan 1 and the outside interface 0 was set to vlan 2

I've been doing a bit of research and from what I can tell I need to set a route outside like so "route outside XXX.XXX.XXX.XXX" with the IP being the default gateway of my ISP, does this sound correct?

I had a quick search an it seems for the ASA you can use: route outside 0 0 gateway-IP

The command is just seting up a static route saying any packet going to 0.0.0.0 0.0.0.0 (which is everything, unless a more specific route is in the routing table), then send it to the gateway-IP.

I'm not sure about the ports defaulting to vlan1, it doesn't hurt to set one just to check. General rule of thumb is never use vlan 1 anyway, it can cause problems when connecting to badly configured switches, or at least that's my experience.

"ip address pppoe setroute" according to the documentation, is supposed to set the default route via the pppoe connections gateway, so I'm not sure that you would need a default static route.

What does the output of "sh route" look like ?

If you log into the asa and run the following command "ping outside 8.8.8.8" do you get any response?

try logging into the web interface & running either applet ASDM or the standalone app version, then you can play with the wizard interface.

From the ASDM you can do the config as per the commandline connection or via GUI
