Dear Edward , sorry , for the lack of information ... I have an ADSL connection , dynamic ip , ADSL router configured under eth0 please give me some directions about this , because a while ago , I enter the setup , and activate some definitions of the firewall and later I couldn't connect to the internet ... so I had to make a new connection using adsl-setup , and it trow me a lot of errors ... but fourtunately I can use internet , but I have serious doubts about the iptables configuration . for example if I use nmap or netstat and test localhost , it says to me that the port 25 is open ... if I use the IP that my ISP gave me , it says that the port 25 is closed.. thanks in advance for the answers , greetings Richard karcher --- Edward Dekkers <edward@xxxxxxxxxxxxxxxxxxxx> escribió: > RGKärcher wrote: > > hi guys , > > > > I want to ask you , about the Iptables > configurations > > ... > > > > When I run nmap ,it says me that I have an > specific > > port open ... > > > > When I do a web test of open port at > > http://scan.sygatetech.com/prequickscan.html > > > > Its says me another ports open or closed .... > > > > when I run netstat it says me another completely > > different thing ... > > > > I dont know what to trust ... > > > > for example I want to close the udp port 111 and > icmp > > 8 .
