I have conflicting range of IP for site A and site B. we use a NAT router in between. we passthrough traffic that doesnt require NATing.
we have a website on siteB(abc.siteb.com) that siteA has to access.
we found out that the DNS server replicate all siteB.com over, and therefore when the user type abc.siteB.com, it go direct to the siteB.com zone and searches for the real address of "abc" instead of the NATed ip.
How can I solve this issue?
