Smoothwall HTTPS

[jsnetman]

Hi All

Just setup smoothwall as an internal proxy with ISA on the edge of the network. Seems to be working but we cannot access any HTTPS sites. My users are screaming for gmail. Smoothwall support is not open, I need info quick.

Support agents are in - there should be someone on the end of a phone now

On a more diagnostic note... I presume the smoothie is set up as a regular proxy?
What's the failure mode for HTTPS?
Is ISA an upstream proxy of the smoothwall?
What's in the logs, both smoothie (info/logs/web filter) and ISA access logs?

I switched off the proxy on ISA

So you are using ISA as an upstream proxy?
First, one suggestion would be to not do that, and allow the smoothie direct network access through ISA's NAT.
Second - it would seem that you *might* have ISA set up incorrectly - have you tried HTTPS proxy directly through ISA?

[jsnetman]

HTTPs works directly through the ISA. Tom Holstock had a good hunt around the ISA server and did not seem to think it was misconfigured. But still no HTTPS when smothwall is enabled as the proxy and ISA straight through.

[tom_newton]

Would it be possible to let the smoothie pass straight through?
I've had a look round to see if I could find any info on "error 13" - it *could* be related to compression, but we don't turn that on...

I think Jason tried that and HTTPS works, but the way it was left is that it was not filtering anything.

[tom_newton]

I can get Jason to put it back like that if that's helpful?

We'll run this past a few proxy experts at some point soon and see if they can shed any light.

No problem, I set it back to my old filtering system in the meantime Jason is going to ring and see if he can find a solution.
