I used a local ISP in Columbus, OH for about 2.5 years before finally
deciding to get a cable modem at least for the summer so I could do
most of my work from home this summer.  I doubt I'll go back to a
dial-up connection - the speed is nice, but the main benefit for us is
it doesn't tie up the phone and it's nice not to have to wait for it
to connect.

I set up a Linux IP-Masquerade server for my church so all the staff
could access e-mail and the web through it and was using worldspy.com,
but they just sold out or merged with Juno and I think you need their
special Windows software to use Juno.  Worldspy was a normal pap ppp
setup so I may see if I can use freewwweb.com now for the church.

Here's the short version.  This assumes your LAN is 192.168.1.x.

Put this in /etc/rc.d/rc.local
# default policy for forwards is DENY
/sbin/ipchains -P forward DENY
# masquerade local network
/sbin/ipchains -A forward -s 192.168.1.0/24 -j MASQ

Also:
echo 1 > /proc/sys/net/ipv4/ip_forward

Then tell all your other machines to use your Linux machine as their
gateway.  You'll probably want to read more about ipchains to disallow
incoming connections.

Here's some more of my "firewall" rules:

# rr-in chain for road runner
/sbin/ipchains -N rr-in
/sbin/ipchains -A input -i eth0 -j rr-in

# allow ident requests from everyone
/sbin/ipchains -A rr-in -p tcp -s 0/0 -d 0/0 113 -j ACCEPT

# reject all ppp interface packets with a source address of 192.168.1.0/24
/sbin/ipchains -A rr-in -s 192.168.1.0/24 -l -j DENY

# allow wget to work - return ftp data only  (ftp-data) but only
# through ports 1024-5999 and above 6010 (6000-6010 is for X11)
/sbin/ipchains -A rr-in -p tcp -s 0/0 ftp-data -d 0/0 0:1023 -j REJECT
/sbin/ipchains -A rr-in -p tcp -s 0/0 ftp-data -d 0/0 6000:6009 -j REJECT
/sbin/ipchains -A rr-in -p tcp -s 0/0 ftp-data -d 0/0 1024:5999 -j ACCEPT
/sbin/ipchains -A rr-in -p tcp -s 0/0 ftp-data -d 0/0 6011: -j ACCEPT

# reject all incoming tcp connection initializations
/sbin/ipchains -A rr-in -p tcp -y -l -j REJECT

# reject all incoming ping requests
/sbin/ipchains -A rr-in -p icmp --icmp-type echo-request -l -j REJECT


The IP-Masquerade HOWTO and ipchains/firewall (can't remember which
one it's called) HOWTOs provide lots more details, although I found
the Masquerade HOWTO much easier to read.

Thanks for the info on freewwweb.com

Dave
