By default the rp114 will do dhcp for the first 30 ip addresses or so
in a 192.168.0.x class c block.

The RP114 can act as a pass through DNS server. By default it passes
its own IP address to DHCP clients. On the setup screen of the RP114
you can set the DNS servers of your ISP. It is also possible to put
the ISP name servers in /etc/resolv.conf as nameservers and bypass the
RP114.... nscd is a big help with name services through the RP114.
i.e. nscd is a good thing.
chkconfig nscd on

Yes, adding lines like this to the host file can help.
192.168.0.2 dhcppc2.my.nat.localnet dhcppc2
192.168.0.3 dhcppc3.my.nat.localnet dhcppc3
192.168.0.4 dhcppc4.my.nat.localnet dhcppc4
192.168.0.32 dhcppc32.my.nat.localnet dhcppc32
The fullish list is important for some, recall that DHCP might get you
an address different than dhcppc2.

Note that you can also use fixed IP addresses in Linux and the RP114.
I would suggest that you save a block of 10 IP addresses for specific
hosts on your personal internet. Something like 192.168.0.40 --
192.168.0.49. Then in the NAT port forwarding screen of the RP114 you
can open a port or range of ports to a host (ssh, smtp, ftp, torrent).
DHCP and NAT port forwarding is a pain...
I like and use the RP114..
I have a friend that only knows how to use ftp for some stuff. I keep
ftp nat/forwarded to 192.168.0.140 and when I need to open it up for
her I just backspace over the 1 I.E. I toggle 192.168.0.140 <-->
192.168.0.40 as needed.
This trick makes it easy to open or lock ports. When I know I am home
I can lock ssh and never see the dumb ssh probes...
When I am loading a new version of any OS I close my inbound ports
until I have all the updates loaded.
The RP114 is not as nifty as firestarter and all the stuff that can be
done with iptables and Linux networking but for the money it has been
a very good little box. It has a DMZ feature that can let you bypass
the RP114 and expore the richness and dangers of Linux networking (or
At the hardware level I do find that the RP114 had smallish problems
as a switch with full duplex and 100baseT. I bypass that...
