使用客户自己的DNS无法解析到地址
00245 2010-3-31 15:33:41 NBR1200G: %7:DNS: get free cache index = 9
00246 2010-3-31 15:33:41 NBR1200G: %7:DNS: Request Id=30
00247 2010-3-31 15:33:41 NBR1200G: %7:DNS: send request to 202.102.252.3
00248 2010-3-31 15:33:42 NBR1200G: %7:DNS: recvfrom request error, errno=5!
00249 2010-3-31 15:33:44 NBR1200G: %7:DNS: kill task Dns30
更换DNS后，可正常解析到：
