Why is the trust interface down? Thats your first hurdle.

Its down as I took it of the network temporarily until I can get someone to
help me with it. I just pulled up the settings from that to see if I messed
up the trust ip's/. Not sure if I got the manage ip, trust ip and gateway
correct. When its connected to the cable modem it will pull an ip from
that.I'll hook up my laptop to it and it will get an ip.I can use the webgui
to get to the management screens buts as far as it will let me get. Can't
get out to the internet with it. Do I need to setup the bandwidth useage
(how if so?) or any other policies. I have had it reset to default. I
connected the terminal cable to it to only pull the settings on the trust
side incase someone notices something there.

Okay, there wasn't enough config/status posted in your first message
to determine if something was right or wrong or what the problem was,
other than you were showing the interface as down.

Otherwise, the bit you posted looked okay.

First steps to troubleshoot your problem.

Make sure you can ping outwards from the firewall and get to your
next-hop gateway.

Make sure that you have a default static route installed.

Make sure that you have a policy from Trust->Untrust allowing All-All-Any.
(not every network wants this policy, but it is a default policy, and
lets outbound traffic get out).

If you are doing NAT (IIRC, you were), make sure the default any
outbound policy has the NAT flag checked.


You do NOT need to worry about bandwidth setup, or logging or usage at
this point. Your basic setup is to put the IPs on the interfaces,
setup the default route, and check on your policies. The policies and
interfaces are what you need to worry about starting out.

Ok. Everything was setup right from what I could tell. From what I could
tell I had to change the bandwidth on the trust interface from 0 to
something.I matched the untrust and trust with 1024 and it works.I was able
to ping but unable to move traffic thru the web browser, Now I have to get
help on the vpn setup.I dont know if this is possible but I would like to
setup a group and then just add users as I need or take away.I am
essentially trying to learn this and a cisco pix501 to be able to set them
up and have multiple sites connected together.
