# How much should I charge to setup a LAN?

I've got kind of an opportunity here - at my client's, there's a "server,"
which plugs into the DSL, dynamic IP which hasn't changed in what seems
like months, and 7 computers and a (an?) HP plotter on 10.0.0.0/8 .
5 of the boxen are W2K only, and the 2 which are mine are Slack 10.0/
W2K.

All I have as far as servers go is IP masquerading and samba, so it's not
much of a server, but that's what everybody's calling it. To the lusers,
it's just S:.

The closest thing I have to a firewall is, as I say, IP masquerading:
-----------------------------------------
[email protected]:~# cat /usr/local/sbin/masq-on
modprobe ipt_MASQUERADE # If this fails, try continuing anyway
iptables -F; iptables -t nat -F; iptables -t mangle -F
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A INPUT -m state --state NEW -i ! eth0 -j ACCEPT
iptables -P INPUT DROP #only if the first two are succesful
iptables -A FORWARD -i eth0 -o eth0 -j REJECT

Maybe I should have asked some time ago - am I shooting myself in the foot
with this setup? (everything in the setting up has been copied and pasted -
I really don't understand the file formats and stuff yet - on iptables,
basically I can't figure out which is supposed to be INPUT and which is
supposed to be OUTPUT. I suppose it's in the FM and I just haven't stumbled
across it yet.)

The "check your ports" websites all seem to say "all ports are closed" or
"all ports are stealthed", so to put up a mailserver, which is about all
I'd need in addition to the samba; Apache seems to come up automagically;
is open the ports, but that would call for some protection, or am I guessing
in la-la-land?

Meanwhile, things are slow at the shop, and the guy's looking for make-
work for me, so what's a reasonable amount of money to ask for to set up
a "real" LAN? I know I could have it done in a day, but since the fringe
bennies are incomparable, I'm working for $15.00/hour, and I'd like to milk a LAN setup more than$120.00.

What does one of those guys who works in a zoot suit and pomade charge for
something like that?

Thanks,
Rich
