Hi

Telnet is also not working.
I am not able to telnet to server1 from server2. But I am able to connect with telnet from server3 to server1.

Thanks

Is server3 acting as purely a router or as a firewall?

Server 3 is purely for Gateway only. There is no software and hardware firewall is used.

Note: I saw that there is single NIC in Server1 but 4 virtual IPs. All Ips are from same network and all are having same netmask 255.255.255.0.

Firstly I didnot consider it but now I think there may something about it. in netstat -nr also all IP is gateway for same network.


Could it be the reason ?

Thanks

Where is the hardware firewall, does this affect the picture, what is it doing?

Have you tried using ssh to each address?

When you successfully telnet from server2 to server1 where does telnet say you are connecting from? Eg do it a couple of times then see what it says on the successful login prompt.

Also, when you are successful, do a netstat -a and look for your connection pairs that refer to your tcp connection, this will tell you what IP addresses are being used at either end for the session.
