IP Networking

Hi guys,

I'm in the progress of setting up a private network in our Sun solaris platform.

Existing ip: 172.16.102.101
New private ip: 192.168.2.3
Netmask is the same for both private & public 255.255.255.0

After setting up the ip, I'm able to ping this private ip address from our workstation, with the ip 172.16.101.120. Why is this so? Supposingly we are unable to ping from outside.

Appreciate any helps here...I'm quite new in network field.

Thanks in bunch!

Make sure you changes into atleast 3 files
ipnodes
netmask
hostname.xyz

Thanks for a reply!

I just found out the reason y we are able to ping the private network from our local workstation.

I did a tracert on the command prompt:

[ISS] C:\>tracert 192.168.2.1

Tracing route to 192.168.2.1 over a maximum of 30 hops

1 <1 ms <1 ms <1 ms 172.16.101.254 <- PC gateway
2 <1 ms <1 ms <1 ms 172.16.102.200
3 <1 ms <1 ms <1 ms 192.168.2.1 <- private ip

After disable the private network on 172.16.102.200,

[ISS] C:\>tracert 192.168.2.1

Tracing route to 192.168.2.1 over a maximum of 30 hops

1 <1 ms <1 ms 1 ms 172.16.101.254
2 172.16.102.200 reports: Destination host unreachable.


Not sure why the tracert pass through 172.16.102.200. Any ideas?

What is the address of the PC you R tracerouting from?
What verison of Solaris?
Does the sun box have 2 interfaces ?
Is the sun box routing?
What is the /etc/defaultrouter file contain?
Are you using ipfilter ?
