1. Multiple Networking problems (semi-newbie)

Hi there,
  you might have seen me asking the same questions around, and if I'm
asking again it's because I could not find my notes again and I never
actually learned about those phenomenon, anyway, here I go:

  I have just installed Redhat 7.1 (Seawolf) on my Celeron433, it has
two Ethernet cards, one "eth0" is connected to my ADSL modem that I
connect with rp-pppoe.  The other "eth1" is for my LAN and I always used
a static address on it, though I'm considering the use of DHCP if it's
not too complicated.

  The idea is that I'm not the only one using this computer, but I'm the
only one that administrate it.  And some services are deeply needed
right now such as IPmasquerading so the LAN computers can access to the
internet through my computer.

Here are my ipchains chains:
Chain input (policy ACCEPT):
target     prot opt     source                destination          
ports
ACCEPT     udp  ------  dns2.sympatico.ca    anywhere            
domain ->   any
ACCEPT     udp  ------  dns1.sympatico.ca    anywhere            
domain ->   any
ACCEPT     all  ------  anywhere             anywhere              n/a
REJECT     tcp  -y----  anywhere             anywhere              any
->   0:1023
REJECT     tcp  -y----  anywhere             anywhere              any
->   nfs
REJECT     udp  ------  anywhere             anywhere              any
->   0:1023
REJECT     udp  ------  anywhere             anywhere              any
->   nfs
REJECT     tcp  -y----  anywhere             anywhere              any
->   x11:6009
REJECT     tcp  -y----  anywhere             anywhere              any
->   xfs
Chain forward (policy ACCEPT):
Chain output (policy ACCEPT):
%

I wonder what are the REJECT lines for?  And what I should do exactly to
make it to work...  Then I would like to know about good documentation
about all this, so I can learn about it.

Next problems are with the servers, I need to setup a HTTP server and a
FTP server, etc...  But let's just start with ipchains for now...

Thanks a lot,
  Simon
