[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 ,
