I have 2 servers, server2 can receive h.264 stream from server1. I need my iPad can play the h.264 stream, and my ipad and server2 are in the same local area network， but can not connect to server1, so I need server2 relay the h.264 stream to my ipad, who has one good solution ? thanks!
Your question is rather vague.
If you are playing via HLS then you could install an HTTP proxy on server2.
Apache even has a proxy module which lets you make a URL on server1 appear as if it was hosted by server2 without having to configure your iPad to use server2 as its proxy.
http://httpd.apache.org/docs/2.2/mod/mod_proxy.html
See the bit about reverse proxy.
