service network restart

Welcome to LinuxQuestions! :)

Is your network connection wired or wireless?

Play Bonny! :hattip:

dundu i have check everything but couldn't get any ping reply except from the server ip itself. I am using wired connection.

Are you iptables is on ?

Try after flushing it

root# iptables -F

Whats output of

root# ethtool eth0

Does it showing connected ?

I got this reply
# ethtool eth0
Settings for eth0:
Link detected: yes

Can you let us know output of

route -n

and involved ips

Thanks
