[7.500][BUG][NOTABUG] HTTP - can't access own server

Hello,

following issue:

When I try to access my OWA from external everything is working as expected, but when I try this from internal over the proxy using the external address the connection fails (timeout).

The log says
2009:09:28-10:22:52 gateway httpproxy[11328]: id="0002" severity="info" sys="SecureWeb" sub="http" name="web request blocked" action="block" method="GET" srcip="192.168.x.xx" user="" statuscode="502" cached="0" profile="REF_EsGuIhjYWX ()" filteraction="REF_DMOklZtcpJ ()" size="2264" time="60380 ms" request="0x84d44a0" url="https:///exchange/" exceptions="" error="" category="119" reputation="neutral" categoryname="Health"


This was working on 7.405...

My fault?
  • Definitely, don't exclude External (Address) as a destination - that, in effect, disables IPS!  So, if the trick I suggested with it as a source didn't work, there's no other choice than disabling that rule.

    Let's hope for rule-wise IPS exceptions in V8!

    Cheers - Bob
