Hi Nathan -
Shouldn't be a problem - re-run the ICW and select the nic attached to the
new ISP's router as your external interface. All outbound internet access
will be directed through this interface. Since you were previously using
the old ISP's router, its subnet should already be excluded from the LAT in
ISA. As a result, ISA will treat it as an external interface. Since packet
filters in ISA are not interface specific, ISA should be listening for
inbound traffic on port 25 on both external interfaces (old router & new
router). As a result, you should still be able to receive email via SMTP
from the old ISP's connection. In addition, you shouldn't have any break in
email, because as soon as the DNS changes propogate, email will be sent to
the new public IP address which you are already listening for email on.
