PIX interfering with web pages?

Hi, I'm running into a bizzare issue that i cannot pin down.

If i try to access www.nmh.org from outside of my PIX, it works fine. If I try from inside the PIX, reliability is about 5% that the page will ever show up. The website is pingable from inside, on a packet sniff from the browsing machine i see the inital handshake and a http Get command, the ack from the webserver, then [TCP Previous segment lost] Continuation or non-HTTP traffic.

I do not have these problems with any other site that I know of.

What should i look at next?

I already have "Fixup protocol http 80" configured on the box.

could you try dropping your mtu on the outside interface and test again?
