Oups, wrong forum, how to change it ? Thanks


Hi all,

I need you advise and experience. We have a CISCO ASA 5510.

We also use an ESX server. On one VM, randomly, the server is not accessible from the outside, but ok if connecting from inside (thus without going through the ASA).

The fix it temporally done by Disabling and Enabling the VNIC (network card) on that VM under Windows. This way, the link is up again.

I am wondering if the CISCO has the ability to block traffic going to any MAC address. That web server receive a lot of request.

I am wondering too if the ASA block that traffic until i make that Disable/Enable (maybe that action reset any ID or something else on the ASA, arp table, etc ...).

If i am not clear, please let me know,

Thanks for your help,

I don't understand your question. You can deny traffic to a certain mac adress, but it's done by ACL. Do you have an IPS module on this ASA? If so, is it configured and could it be blocking traffic?
