Linux system as a router

How do I set up iptables to make the linux system function as a router?
I think I need to set forwarding between the two interfaces, but I don't
understand the syntax of the command.

Thanks,

David A. Kirkwood

Re: Linux system as a router

If you are doing NATting at the router you need a rule such as 
iptables -t nat -I POSTROUTING -o eth0 -j MASQ if you have a dynamic address, or
iptables -t nat -I POSTROUTING -o eth0 -j SNAT --to-source 1.2.3.4 if you have a static address

you also need net.ipv4.ip_forward=1 in /etc/sysctl.conf

Then have your default route go out your WAN interface.

echo "1" > /proc/sys/net/ipv4/ip_forward

It's been a long time, but If you want to connect to another modem you need to use a terminal program
like...minicom (maybe I don't remember the names)
 
If you just want to dial with the modem you can do something like:
echo "ATDTphonenumber" > /dev/modem
pick up the actual phone
echo "+++ATH" > /dev/modem
 
ATDT is AT (Attention) D(Dial) T(Tone) - Use tone signals to dial (as opposed to pulse)
 
+++ is modem escape
 
ATH is hangup the modem

Python

I'm trying to decipher a pythom script someone gave me for
administration and I can't figure out what the symbol 9[18] means in a
regular expression as in

 re.compile('MezsageXYZ,9[18]\d\d')

I have most of the rest of it figured but I can't find this in the
Python book I'm using.

All help is appreciated,

Re: Python

9[18] will match either "91" or "98".

-  
Thanks,

Chris
