Jay B.,

THANKS for the response...

In my original post I explained that I have two systems that are configured for 
my network. One an OLD system running 08.04 LTS (that can NOT be upgraded) and a 
NEW system running 10.04.2 LTS.

The configuration files for /etc/dhcp3/dhcpd,conf, /etc/dhcp3/dhclient, and 
/etc/network/intefaces on both systems are the SAME except OLD uses eth1 & eth2 
and NEW uses eth3 and eth4  (I have used diff to verify). The same goes for 
/etc/hosts and /etc/resolv.conf. Are there any others I have missed???

The OLD one works just fine. The NEW one does also, UNTIL I bring up my laptop's 
bowser (Firefox) or e-mail (Thunderbird) then NEW drops the connection to the 
net. The wired systems work with BOTH

My network consists my Firewall system (either OLD or NEW) with an access point 
(Belkin 54G Wireless G Range Extender/Access Point-configured as an access 
point). a connection to a 5 port hub (all five have a connection to a wired cat5 
port one of which is the Access Point) and a connection to a Time Warner 
Roadrunner cable modem. Both have 3 NICS (one built in and two PCI cards).

I have two subnets 192.168.xxx.0/28 and 192.158.xxx.32/28

I do not use a proxy, no duplicate IPs, I have NOT done a trace route (never 
used it, so I will have to read up on it) if you need some traces. What routes 
do you want to see?

Thanks,
Jay R.
