clue for the clueless please
This is a Microsoft Passport / Hotmail access question, so if these are alien to you, please move on... Before anyone has a go at me, I have looked on their web site(s) and cannot find any policies or pointers that are outside "forgotten password" land etc. We have turned up a new customer for BGP multihoming with a new IP block from RIPE (217.71.224/20) and in testing we are having problems getting to certain sites. Normally I would attribute this to no reverse DNS (yet), but for Hotmail it is getting weird. The reverse DNS issue is in hand and is awaiting DNS servers to be up etc. The Hotmail issues (and maybe some other sites we have not yet got to) appear to be IP block related. Do "they" do some sort of geographical redirection or filtering based on IP block or AS number ? Testing from another IP (OK, the nearend point-to-point address on one of the routers) which also does not have reverse DNS but is in an older IP block, in a different AS works fine. The problem is the redirection from authentication -> mailbox. It just hangs. Tested with multiple browsers (lynx included ;) and all the same. And pointers would be greatly appreciated. -- Peter Galbavy Knowledge Matters Ltd. http://www.knowledge.com/

What does telnet to port 80 reveal? If you can get short queries back (E.g. HEAD / HTTP1/0) but not longer queries it sounds like a PMTUD problem. Does the new customer have Frame Relay or any other links with MTUs less than 1500? Windows sets the DF bit on outbound packets, and I believe Microsoft filter PMTUD ICMP packets. -- Ryan O'Connell - <ryan@complicity.co.uk> - http://www.complicity.co.uk I'm not losing my mind, no I'm not changing my lines, I'm just learning new things with the passage of time
