hi all there i have configured shorewall using webmin on ubuntu 10.10 with DSL with dynamic IP from ISP. Internet is working fine but Outlook mail are not going ???? Is there anything block or what ??? my policy is as under loc $FW ACCEPT $FW any ACCEPT any any REJECT for internet i define a rule for specific IP to use it Accept loc:{IP} net
Did you open the ports 25, 110, and 143 in the firewall? What's the output of Code: netstat -tap ? Any errors in the mail log?
Thanks for ur response Falko, i share my internet using the iptables rule below 1. iptables -A FORWARD -o eth0 -i eth1 -s 192.168.0.0/24 -m conntrack --ctstate NEW -j ACCEPT 2. iptables -A FORWARD -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT 3. iptables -A POSTROUTING -t nat -j MASQUERADE Then implement Shorewall after sharing internet.... there are policies as under in my shorewall loc $FW ACCEPT $FW any ACCEPT any any REJECT Nothing more than this implemented in my enviornment... Just a rule that allow internet for specific IP as under Accept Zone loc:192.168.1.1, 192.168.1.2 Zone net any Is there any thing wrong here in rules or policies ???
