Can't access the Internet at all.... (newbie)

Hey Guys,

I've read a pile of threads and posts and .pdf files, but I just can't get this setup to click for me, so any ideas if you can...

This is my first time installing and using ASL and I haven't quite gotten it to work right yet.  First, my setup:  P3-450 w/ 256 megs of RAM on a 10 gig HD.  I have 2 10/100 NICs in the system, both are recognized just fine.

Currently I have a cable modem with a non-static IP that feeds a Linksys 4 port Router that has a 16 port switch uplinked to it.  My goal is a simple one:  To eliminate my Lnksys Router and have my cable modem feed one NIC, and the second NIC attach to the 16 port switch so I have much better control of things in my LAN.

After installing ASL I only had 1 Network-> Interface.  (Internal on eth0 - 192.168.1.99/255.255.255.0)  I added a 2nd Interface (External on eth1 - 10.0.0.1/255.255.255.0)  How do I know what IP to use here?  Should this be my external IP?  (Dynamically assigned by my cable modem?)  I've seen a lot of 10.x.x.x IPs, is this just a rule of thumb, guaranteed to work on my end?

I've tried adding a rule under Packet Filter -> Any/Any/Any/Allow and that still hasn't granted me any access.

I can't ping anything externally, I can't resolve any host names, I can't even try to use Up2Date Service.  ("This Up2Date Server is emtpy or not available at the moment.")

I have a domain controller that currently acts as my DNS Server in my intranet, and yes, I've changed the settings on my TCP/IP Settings to hit my ASL server - no change.

I know it's something stupid and simple, but I have no clue where to start....

Any help would be greatly appreciated fellas...

Thanks,

- Magua

If your cable modem is DHCP capable (which many are), you will be setting your external network interface to get its IP and gateway by dynamic (not static) means; when you select dynamic, you will not have to enter an IP address for an entry...

... and once that NIC has an IP and is up and active I should be good to go with the settings I've mentioned?

     "I have a domain controller that currently acts as my DNS Server"

Well, your name resolution won't work unless you configure that domain controller's DNS to pass-off queries to the Internet -that's a Windows configuration issue. I know there are numerous articles on how to do it that a Search engine will readily locate.

Make sure your ICMP and ping are enabled under the ICMP section; let's change that 'Any'  service rule to just two rules for HTTP and DNS only (to start):

     Internal =-->Any Allow

If you want to see if it works, just use a DNS on the Internet, as opposed to the DC, to start.

If that's still failing, post the results of your pings and traceroutes (sanitizing your IPs for privacy, if you prefer)
