Hi 

I received a useful reply on how to set up a 192.168.xxx.xxx network
next to my existing one, but I am still not quite sure on how to
implement the changes. Aor my gateway and router I am running linux 6.2
(kernel 2.4.2-2) with iptables-1.2.1a-1 and iproute-2.2.4-10. I have
received instructions from Jerzy Jamrozy, and below are the answers he
gives and the further questions I have:

Where do I add the information for the second interface? On my linux
machine, do I simply add another gateway entry in the
/etc/sysconfig/network file by adding a line: 

GATEWAY=192.168.0.1

Can someone tell me where to add the requisite information under linux
to define a NAT?  I am using IP tables and I have a firewall script. I
think I may have to put a line in my firewall script, something like: 

iptables -append FORWARD -i eth0 204.49.23.64/26 -dst 192.168.0.0/24 -j
MASQ

Would this both forward as well as masquerade to 192.168.0.0/24?

Hopefully the above line takes care of that? Can someone correct that
line if it is wrong?

Do I have to set up the DHCP on the gateway? I was hoping I could set it
up on one of my servers, then have make it so that the server has an IP
address on the old as well as on the new network.

If someone can help me with the details, that would be tremendously
appreciated. 

Thanks
