Unable to connect to my linux pc from a different network

Asked by LinuxDuke in Linux Network Security, Linux Networking

Hi Experts,

I have a linux server in a DMZ on the following network 172.20.192.0 from this server I'm unable to trace my machine on a different network 10.204.26.0 . The is another server on the dmz on the same 172.20.192.0 network that I'm able to connect to via ssh then ssh to this server that is giving me problems from that server as they are able to ping one another.

The IP address of server 1 the problematic server is correctly configured on eth0
My Kernel routing is :
[root@server1 ~]# route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
172.20.192.0    *               255.255.255.0   U     0      0        0 eth0
169.254.0.0     *               255.255.0.0     U     0      0        0 eth0
default         172.20.192.1    0.0.0.0         UG    0      0        0 eth0
[root@hdk ~]#

I deleted the 169.254.0.0 network but after restaring the network it came back. I have looked at the /sysconfig/networking and network-scripts all looks fine. I'm not sure where this ip is coming from.

This is the output of the route command from the machine I able to access from the 10.204.26.** network:

[root@server2 root]# route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
172.20.192.0    *               255.255.255.0   U     0      0        0 eth0
127.0.0.0       *               255.0.0.0       U     0      0        0 lo

What am I miss or what am I doing wrong your help is highly appreciated.

The Duke
