Good, so it works with HTTP/1.1
Depending on your mod_gzip rules, you might return gzipped content
for HTTP/1.0 if the browser sends Accept-encoding: gzip
It was the default in IE 5(?) that if IE was using a proxy, it would
use HTTP/1.0 by default, although there was a checkbox to use HTTP/1.1
(many proxies are broken messes and HTTP/1.0 was more compatible)

Now, what is the ServerIron sending for transactions through it?
What do your access logs say?  HTTP/1.0 for all requests?
HTTP/1.1 on some?  Which, if any, are getting compressed content.
Try modifying your access log to also log the contents of Accept-encoding
if present.  What do mod_gzip specific log parameters tell you?
See the LogFormat example at
