I am running Mdeamon mail server in the office behind a pix 501. Recently external users have been unable to connect to it whilst internal is fine, once i open IE or  telnet from the mail server the external access works fine, then about 4 hours later it goes down again. - any ideas

    It *sounds* like the either the switch the server is connected to or the PIX is losing the ARP entry.

    When that server is not reachable, can you look at both arp tables to confirm?
