[TAG] IPTables + Squid problem

[Deividson Okopnik]

Hello everyone

My old internet server crashed and i had to setup a new one, and im
having several problems.

My squid configuration is pretty simple, I basically allow everything:
Allow manager localhost 	
Deny manager 	
Allow purge localhost 	
Deny purge 	
Allow localhost 	
Allow all

And my iptables config file is empty (exists but is empty -
/etc/network/iptables)

And msn doesnt work on the machines behind the proxy, and noone can
atach files to emails - im guessing no ports are being forwarded
(cause of the empty iptables file) but if I put content in it, eg.:
#!/bin/bash
iptables -F

and do an sudo iptables-apply, it gives me an "line 2 failed - failed"
- what am I doing wrong? btw im on ubuntu 10.04, and allowing any
outgoing connection to any port would be good enough, later Ill think
about the security.
