Not in general, it appears that most of the blocks seem to occur at the DNS level from my experience. However we have seen blocks on port 80 or 443 but infrequently.Are there any issues with general https there also? -- Leigh-----Original Message----- From: Lyle Giese [mailto:lyle () lcrcomputer net] Sent: 27 March 2012 15:39 To: nanog () nanog org Subject: Re: OWA blocked by China On 03/27/12 09:16, Jim Gonzalez wrote:Hello, One of my customers has workers in China.

However if the OWA server is on a dynamic IP or you use a dynamic IP address service for ip address resolution, then it will be blocked all the time by China. It's just the way things are done over there. Lyle Giese LCR Computer Services, Inc.
I have had a customer with sales persons in China for about 10 years now and they are ones that are quick to complain. So we have gone through the cycles of various blocks over the years. But putting their in house server on a static IP address and getting their OWA server address resolution out of dynamic name resolution services seemed to help the most.
