Strange, we have saml1.1 working with a reverse proxy currently, and it had been working well for years. That's on shib 2.<br>
Short of putting the IdP in the DMZ that's the only way I can see to do it, which could be an option I guess. It's far from ideal however.<br>
Cheers,<br>

<br>
You can't reverse proxy the back channel, at least not easily, most older SPs are not going to know to sign their requests and will be expecting to use a client certificate.<br>
<br>
This isn't a change, if you have something working today you would have to set it up the same way.<br>

<br>
Proxying is the same as, if not worse and more invasive than, offloading.<br>
