Yes. Something's broken.
Tell us what your network setup is, and tell us what your ruleset it, and we
might be able to tell you what's broken.

Sorry I was not very clear,
Actualy I removed all iptables rules with:
iptables -F
iptables -X
iptables -Z
but adsl still hangs and does not connect.
Before I started testing iptables it used to connect quickly.
My network is like this:
on eth0: connection to another computer, ip 192.168.0.1 this is ok
on eth1: connection to the adsl modem. I know that this device can not be
initialized on the booting process and I thought that maybe iptables was
initializing it, but I removed all rules and stoped running the rc.firewall
file. This one has dynamic ip. I know that booth network adapters are
working fine, so it´s not hardware problem.

Have you removed your nat rules (eg SNAT in the POSTROUTING chain) as well ?

What do you mean by this last comment ?

Are you getting a valid IP address for this interface from your ISP ?

Can you connect to the Internet from the Firewall machine itself (never mind
the internal machines on your network for now) ?
If you can, then tell us whether you have a SNAT rule in your POSTROUTING
chain to allow internal machines to connect out as well.
If you cannot connect from the Firewall machine, then it is not a netfilter
problem. Check the hardware and the interface configuration. Why do you
say "both network adapters are working fine" ? How do you know ? What
have you tested ?
Antony.

Have you changed the default policies to ACCEPT on the default chains,
e.g.:
$ iptables -P INPUT ACCEPT
$ iptables -P OUTPUT ACCEPT
$ iptables -P FORWARD ACCEPT
That might help
