Which version of Altavista, there were several, as I recall? Also as I
recall ALL of them had proxy problems, and all but the last has serious
DNS security risks (due to the included version of BIND).

I haven't worked on one of those in years, so I am sorry I can't offer
much configuration help.  But, if you are running an older version, this
might be a good time to consider a change.

Can you connect to the site from a client machine on the DMZ outside the
firewall?  Is the site load balanced?  Are your forward and reverse IP
addresses correctly configured?

Do you mean  HTTP redirect, or ICMP redirect?

You should probably look at ICMP filtering, most likely one of you is
hosing
PMTU discovery.

A sniffer outside the firewall and someone who can interpret the data is
your best bet.
