Browser not connecting anymore to a specified port


Hello,
I have a web application on a remote server that responds on the port 444.
On my local PC I have a brand new Mepis.
Everything is fine except this: I cannot connect anymore to my remote application since I installed Mepis. Something is changed but I don't know what it is.
Does anybody know what to check?

Many thanks.

Ciao

You may need to open that port in guarddog.

Well. Right. The door is still closed.
For what I understood about guarddog usage I opened it but at the end it does not work and "nmap" confirmed it.

How would you open that port from command line?
I tried
Code:
iptables -A OUTPUT
With no succes....

Suggestions?

Thanks

You could try;
# iptables -A INPUT -p tcp -m tcp --dport 444 -j ACCEPT
but I have never done just single rules,here is what I just did to get mine to work;

I tried but the port is still closed.
Either before and after a reboot.

Why I'm so lame?

Turn Guarddog off and try this,no guarantee;
# iptables -F; iptables -t nat -F; iptables -t mangle -F
# iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
# iptables -A INPUT -m state --state NEW -i ! eth0 -j ACCEPT
# iptables -A INPUT -p icmp -j ACCEPT
# iptables -P INPUT DROP
# iptables -A INPUT -p tcp -m tcp --dport 444 -j ACCEPT
and your not lame
how do you connect to the net eth0 and a cable modem,what distro did it work with,will it work with the firewall off,does the modem have a firewall ect.
