Hi All

First off all Thanks for taking time to read my post. I need help from network expert.

Currently I have installed Fedora 21 server version on my server with two NIC card (SolarFlare Fibre adapter). Set static IP for both interface as per below.
My issue right now is I'm not able to access my server using external IP (different segment ). scenario as per below

My Desktop IP:10.0.52.215
Can access my fedora server on IP=10.2.55.228
But cannot access using IP:172.16.55.196
My Desktop cannot ping 172.16.55.196
My Desktop can ping other windows machine on segment 172.16.55.X. My desktop can ping all WINDOWS machine with following IP
172.16.55.200 (Windows machine)
172.16.55.191 (Windows Machine)
172.16.55.192 (window Machine)

Following are the configuration on my fedora server

first i would not bother doing anything on fedora 21

fedora 21 will hit it's END OF LIFE and become UNSUPPORTED in November - in about 60 DAYS


install Fedora 22 FIRST
