I've been playing around with altering alias entries on our pix and FWSM. It seems to me there is some timeout in effect when I make changes, clear xlate doesn't help anything.
Example: On my windows network connected to FWSM I have set up one alias to redirect an external mail server IP to an internal one, it's been working fine from my windows PCs. I removed the alias a few days ago and now only get the external IP as ping reply. The problem is that after puting the alias back and doing clear xlate I still get the external IP as ping reply.
My windows PCs are Active Directory connected and use my DCs as DNS servers. Do I have to flush all DNSes after making alias changes?
