Re: [TCLUG:8792] Multiple Ethernet Woes

[Mark Dalton <mwd@sgi.com>]

I will take a look.. Rather than just using /etc/hosts.deny /etc/hosts.allow,
I should have suggested to the others to use 'ipchains', so you can determine
which side of the firewall the person/IP address is comming from.

I will see if I can go and find your message and take a look.

That said:
   1. Can you firewall machine see/connect to the other machines?
	- Does it know the IP address from the firewall and try to
	  connect but fails?
	- Does it connect then fail.
	- What is the netstat -rn and netstat -output?
   2. What happens when your other machines try to connect to/through
      the firewall machine.
   3. What security do you have on for the various machines?
	/etc/hosts.deny ALL:ALL and /etc/hosts.allow
	IPChains? filtering
