actually I'd like to make a correction to this last e-mail.

I did some double checking and a lot of rebooting.

I *can* access the DMZ from both my internal nets (eth1 and eth3).

I can type the private IP address of the DMZ server into the web browser and
I have pages come back.  But, entering in the Public IP address of the DMZ
server  into the web browser yeilds no response (from the internal nets).

I can ping the public IP from inside the internal net(s).  But computers
outside my own network(s) can not ping the public IP. The router can ping
the additinal IP on the external interface.

I replicated this on another Dachstein-CD boot box on another DSL and had
line same problem only this one has just the DMZ and the eth1 internal
interfaces.

sorry for the mis-information but I didn't find this out until I put
together a brand new Dachstein CD 1.02 and loaded it on diff computer that I
am building.


Thanks

Alec

Hmm...I'm not sure what's going on...what IP are you trying to use to
get to the web-server?  The public port-forwarded IP (66.93.80.148 ), or
the private IP (192.168.2.1)?  Exactly what happens when you try
connecting with either IP?

You may have to wait until I can get a test network setup again, switch
to a proxy-ARP based DMZ, or gather some detailed diagnostic information
(since my test network is still sitting in the garage, disconnected
after my office move at the end of last month).  If you want to do the
latter, please try the following:

- Reboot your firewall to provide a clean slate...you might want even to
even dis-connect your upstream link (if you're not using dhclient to
configure the external interface)

- Log in and manually add some packet tracing ipchains rules:
    ipchains -I input -l
    ipchains -I forward -l
    ipchains -I output -l

- Try connecting to your DMZ web-server from both internal networks,
using both IP's above (for a total of four different connection
attempts).

- Run "net ipfilter list >/tmp/ipfilter.list"

- Send me the results of the above command, as well as the contents of
/var/log/syslog, and the files /etc/network.conf and /etc/ipfilter.conf

- Clear your manually added ipchains rules (change the -I to -D in the
commands above) or just re-boot.
