Thank you Sebastián, the web browsing seems ok (I'll see if the problem occur during the next days...)
but I still have problems in sending "large" E-mails (e.g. 1000k) To enable the mail throug my ISP I've added these lines at the end of /etc/shorewall/rules ACCEPT loc net tcp 25 ACCEPT loc net tcp 110 Is this correct? Is there something else I should do? Thank you again Mauro (Sorry I had to cut the Email to be able to send it :-( > Add this line to iptables > > iptables -A FORWARD -o ppp0 -p tcp --tcp-flags SYN,RST SYN -j > TCPMSS --clamp-mss-to-pmtu > ------------------------------------------------------- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.
