still stuck on this :(
I've found that using for a capture filter "tcp and host <<PC IP
ADDRESS>> and host proxy.mycompany.com", whilst is a valid filter,
does NOT do the job I require.
It seems to be the case the actual traffic flow will reflect an IP
address that has a host name of one of the assigned proxy servers by
the main DNS server (e.g. proxy4.domainx.mycompany.com) and hence I'm
guessing due to this the filter does not work.
Any other ideas/suggestions here?
I'm kind of stuck for the moment. Again the challenge is how to
capture traffic only bound through the proxy servers, but for which
you don't really know which proxy server that DNS is going to allocate
to you based on the main DNS proxy name (proxy.mycompany.com).
