Hi all, I've got this strange thing: I setup a openvpn link between two openwrts. NetA: 192.168.2.0/24 NetB: 192.168.0.0/24
In netA there is a mail server + DNS: 192.168.2.44, with domain name branch.abc.com In netB there is a mail server + DNS: 192.168.0.44, with domain name abc.com
I setup both DNS server to be a slave server of each other domain. - From NetA, it is able to 'copy' the abc.com zone from NetB. But from NetB, it isn't able to copy the branch.abc.com from NetA. In /var/log/messages, the error is: mail named[1566]: zone branch.abc.com/IN/external: Transfer started. mail named[1566]: transfer of 'branch.abc.com/IN' from 192.168.2.44#53: connected using 192.168.0.44#50125 mail named[1566]: transfer of 'branch.abc.com/IN' from 192.168.2.44#53: failed while receiving responses: REFUSED mail named[1566]: transfer of 'branch.abc.com/IN' from 192.168.2.44#53: end of transfer mail named[1566]: zone branch.abc.com/IN/internal: refresh: unexpected rcode (REFUSED) from master 192.168.2.44#53 (source 0.0.0.0#0)
I've put allow-transfer in: zone "branch.abc.com" { type master; allow-transfer { 192.168.0.44; }; file "branch.abc.com.zone"; };
Adding to the confusion: - From NetB, doing a traceroute to 192.168.2.44 result is OK. But, when I restart named, the traceroute to 192.168.2.44 brings no response. But, tracerouting to other PC in NetA succeed.

I'm not sure what is causing this, either: 1. Bind configuration error 2. Inconsistent/strangeness in VPN
Any thoughts? Thank you very much. - -- Fajar Priyanto | Reg'd Linux User #327841 | Linux tutorial http://linux2.arinet.org 13:10:54 up 5:02, 2.6.24-18-generic GNU/Linux Let's use OpenOffice. http://www.openoffice.org The real challenge of teaching is getting your students motivated to learn.
