http://www.linuxquestions.org – Hi Guys, I was trying to write IPTABLES script to block the ICMP ping using the below mentioned command in OpenSUSE 11.2 Doing this is VMware..... iptables -A OUTPUT -o eth0 -p icmp -j DROP & then I tried to ping the different computer & it didnt allow me to ping. Then I deleted using the command - iptables -D OUTPUT -o eth0 -p icmp -j DROP then I couldnt ping also. Another thing I found is my firefox is not connecting to the internet as well, but before writing the script, I can connect to internet. I did a "dhclient" & iptables -F.......still no go......any clue...... (HowTos)
