Hi, all I've setup liberty release with neutron-openvswitch using gre tunnel at Centos. I've an problems when iptables service started at network and compute node. Instance couldn't get the internal IP address(DHCP) when it boot, if dump the packet using tcpdump on both of tunnel interface it says like this :
13:03:08.164944 IP 10.24.0.23 > opstcomp1-srg.dev.jcamp.net: ICMP host 10.24.0.23 unreachable - admin prohibited, length 106 10.24.0.0/24 is my tunnel IP network. I've already add this rule on both node but its no luck iptables -A INPUT -p gre -j ACCEPT iptables -A FORWARD -p gre -j ACCEPT Can someone help me to solve this problem ? -- Cheers, [image: --] Adhi Priharmanto [image: http://]about.me/a_dhi <http://about.me/a_dhi?promo=email_sig> +62-812-82121584
