I run dozens of VPNs and am very familiar with MTU issues but after several
captures and debugs, I initially ruled an MTU issue out. No packet was over
~1300 bytes in the capture, no fragmentation...nothing. But sure enough, as
soon as I adjusted the TCP MSS on my router it started working.
Just goes to show take nothing for granted...

Subject: Captive Portal redirect page size limit???
I have the CP working just fine with a small test redirect page. I don't
use any authentication so all my users have to do is click the button that
they accept the terms. However, when I add all the content to my redirect
page (about one full page of text with minor formatting) the redirect always
I worked through this little by little and the only thing I found that makes
any sense is that the page has too much text in it. If I hack it down to a
single small paragraph then it works fine but as soon as I get past that
"magic" number it fails. This problem exists on both IE7 and Firefox so I
don't believe it's a browser issue.
I'm running 1.3b4. Does anybody have any idea what might be causing this?
It's going to be a real problem for me if I can't get this working.
