RE: [newbie] Network problem

So you have a router at 192.168.1.1?  Post the output of:

 

ifconfig

arp -n

iptables -L -n

Subject: [newbie] Network problem

Hi,

 

New on this list, and new Mandrake user (have some experience with OpenBSD - command line versions, not X).

 

I'm setting up an mail server behind a firewall (Postfix and Mandrake's pop3). My problem is that it only works in the internal network. When I try to ping or trace "the outside", I get "Network unreacheable". My firewall has port 25 open both ways, both UDP and TCP.

Routing table:

 

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         192.168.1.1     255.255.255.0   UG    0      0        0 eth0
192.168.1.0     *               255.255.255.0   U     0      0        0 eth0
127.0.0.0       *               255.0.0.0       U     0      0        0 lo

Any suggestions would be helpful - I'm running out of time...

 

Regards,

 

Ralph Utbult
