[Shorewall-users] Why shorewall doesn''t working with my configuration ????
What''s happening with my firewall ? I''m using MNF 8.2 My router is ADSL and has a public ip 213.13.127.176, and the private is 10.0.0.1 The mail server is in the lan and it''s a exchange server and I just want to retrieve/send the mail to my ISP (smarthost) . I try to telnet on port 25 from the lan to wan (194.65.3.55) but don''t work. If I do a ping from the firewall to 194.65.3.55 it works fine. My configuration : Lan - eth0 - 172.31.0.1 -255.255.0.0 Dmz - eth2 - 192.168.0.1 - 255.255.0.0 Wan - eth1- 10.0.0.2 - 255.0.0.0 -Gateway is 10.0.0.1 (router) My routing table : 172.31.0.0 * 255.255.0.0 U 40 0 0 eth0 213.0.0.0 * 255.0.0.0 U 40 0 0 eth1 10.0.0.0 * 255.0.0.0 U 40 0 0 eth1 127.0.0.0 * 255.0.0.0 U 40 0 0 lo default 10.0.0.1 0.0.0.0 UG 40 0 0 eth1 - The Masq is : - Eth1:0.0.0.0/0 172.31.0.0/16 213.13.127.176 Eth1:0.0.0.0/0 192.168.0.0/16 213.13.127.176 -The firewall policies and rules are default which allow to telnet on port 25 from lan to wan. -I'' m watching /var/log/syslog and there is no entry about the connection above - Web proxy is working fine. Thanks ,
