I've got two small companies, each with their own subnets. CompanyA is on 10.10.1.0 and CompanyB is on 192.2.900.0. A Windows RRAS dual nic computer is acting as a router between the two. Each subnet can ping each others computers.
The problem is with DNS. I would like to have CompanyB DNS listed as a Secondary zone and vice versa. I have checked the Zone Transfer to any server, on both DNS servers.
However, when the Secondary Zone is added, DNS reports that 'the transfer of the zone from teh master server failed', with the DNS server recieving the 'red cross' treatment !
Do I need to do anything special to allow DNS traffic over the router ? It's odd that the two DNS servers can PING each other, but cannot transfer data. I'm sure I've allowed all permissions.
