Default TLSv1 not being handled correctly thru NBM


I have NBM 3.8.4 installed on a netware server 6.5.7. I cannot hear
streaming audio from a site that uses ssl/TLSv1 to establish the
encrypted link. It seems to be a streight 443 connection according to
the trace. I tried bring down the filters but it still doesn't work. I
did a packet trace and I see that the certificate was not sent by the
server and the workstation I was using send a fin/ack/rst to the
server. If you would like to see the capture files. I have one for a
good session (beyond the firewall) and one bad session behind the
firewall. I was thinking the problem could be in the https filter
because it is a stateful filter. Could it be I need to split the filter
in to incoming and outgoing???? Any Ideas???

Default Re: TLSv1 not being handled correctly thru NBM

443 is 443 in terms of the filter exception, whether tls or ssl, etc.

You said that it did not work even with filters down, which tells me
you have a proxy issue, not a filtering issue.

Try patching the server per tip #1 at the URL below, and tuning it per
tip #23 and 63. If using IE, set http 1.1 thru proxy in advanced
settings, and see if that helps.

Might help if you posted the link you are using so others can test
against it, if it is publicly available.
