IPCop dropping an alias?

I'm looking for some ideas here... i have an IPCop machine with a
primary IP of xxx.xxx.xxx.005 and aliases of xxx.xxx.xxx.002-010 on
the red interface.

I have a few machines in the dmz, no problems, and some port
forwarding in to the trusted lan, no problems.

I have an Exchange server in trusted (green) that was not accessible
from the outside, and while I had an external IP in the dns for it at
xxx.xxx.xxx.004, it was not turned on.

Then I wanted to be able to use my Apple laptop to access it from
outside the home network, so turned on the xxx.xxx.xxx.004 alias and
configured my various apps, mail, address book to access everything
via IMAP, IMAPS and OWA...

Everything was falling in to place - but for some reason, when that IP
receives much traffic the address goes dead - i have to turn off the
alias in IPCop and then turn it back on for it to work again... which
only lasts until I fire up Mail and try to sync up the IMAP mail.

Anyone have any ideas on what would cause this? I'm pulling what's
left of my hair out trying to solve this one.

thanks all,

Richard

Make absolutely certain you are not sticking those leading zeros in the
addresses. xxx.xxx.xxx.005 might equal xxx.xxx.xxx.5 but xxx.xxx.xxx.008
and xxx.xxx.xxx.009 are invalid numbers - the leading zero means you are
writing in OCTAL (base 8) and not decimal.

No, i'm only using the 000.000.XXX for an example...

BUT - i did learn something as i've played with this - it appears to
just drop the alias after 5 minutes. If i deactivate the alias, or
delete it, and put it back on / re-enable it... the address comes
alive, I can ping it, etc..

then after 5 minutes it dies.

All other aliases work fine - ideas anyone?
