My MX record still point to address assigned using the block of addresses we had with the old provider. These still still be valid because the circuit is up. And our firewall and the Cisco router NATs the true internal address to a valid public address. So it seems that I should still be able to at least recieve mail through the old circuit until the DNS changes settle in.
But I'm apparently still overlooking something.

Both have active connections tot he network segment where the unprotected interface of my firewall lives. E-mail comes and goes just fine through Provider A when I set its router as the default gateway on my firewall. When I set up provider B's router as my default gateway I can send e-mails fine, but can't receive them. I know that the required DNS changes showing my new addresses haven't filtered through yet. My question is, when I'm using my new provider as my default route to the 'net and some one sends an e-mail to me at [EMAIL PROTECTED], shouldn't it still be able to come in via my old (and still activeand connected) internet connection and be delivered to my exchange server? Configuration: Exposed firewall a.b.c.180 /29 network Old connection (A) a.b.c.179 /29 network New connection (B) a.b.c.177 /29 network I'm probably missing something totally obvious here, but hey, a chance to learn is a chance to learn.
