There are 2 internet exports of telecommunications and mobile in some site, the requirements of all users of the Internet are gone telecommunications outlet. Telecommunications and intranet domain configuration of NAT outbound, it found that the telecommunications user access to telecommunications website normally, but it can not open the page of the mobile site.
As customers required all users on Internet only go telecommunications exports, configure policy routing in internal domain, to force all intranet users take the telecom exports, thus avoiding the problem of the investigation of specific routes go mobile interface to access the mobile site.
The configuration plan is as follows: internal network interface is a trust region, internal network segment is 192.168.100.0/24, make a policy-based routing in trust region, to force the source address is an address of 192.168.100.0/24 segment, and the next address is telecommunications exports 220.127.116.11.
Through the internal PC tracert, Intranet users access the mobile site by mobile exports after checking the the detail routing table, after check the domain between mobile and internal network, the domain is not configured NAT outbound, so it did not make the address translation when internal network users access the mobile site, so it is no working.
