ICMP traffic will not traverse

[Michael Hart-Jones]

I am having an issue with my servers.  The setup is as follows Management Server, Host1 and Host2 Centos 6.2 Cloudstack 3.0.2 The server was setup by a collegue who has left since but I have noticed that we do not have the ability to send ICMP traffic to our virtualised hosts, prime example being ping. I can see he has setup basic networking, and I do not have the time to try and change this over.  I have tried to setup the security policies to allow it but I cannot get any response.  Has anyone got any ideas where I should start looking? --- Michael Hart-Jones BEng         E-Mail: mhartjo...@accessit.co.uk Tel: (01227) 750555 Fax: (01227) 750070 ************************************************************************************************* Disclaimer: This message may only be read in context and with common sense.  If concerned by it or in doubt, please destroy it. If this message is not meant for you,  we have made a mistake and would appreciate your help. We promise that we mean  no offence and will endeavour to rectify our mistake.  Our full contact details can be found on www.accessit.co.uk Company number: 3117204 *************************************************************************************************
