I need help with IPCop.

[Lisa Kachold]

Hi Eric,

It looks like you have the subnet, gateway and ip address setup
correctly for your webserver.

I think your issue is with the DNS server in the green zone.  Are you
sure that your dns is working?

What part is not working?

# ping [gateway on ipcop]

# nslookup apple.com

# ping apple.com

and on ipcop to assist to see what it's getting use:

tcpdump -v -i eth1 (or whatever interface you have it set for)
