Proxy DNS
« on: February 02, 2014, 09:17:49 am »
Good day,

 I have built few vpn tunnel with my workplace. Everything work fine.

I'm already using proxy DNS, so all the dns query on my lan pass through the SSG140 (that I use at home). That work fine.

Since I built the tunnel, I have added an entry into the the proxy dns:

set dns proxy
set dns proxy enable
set interface ethernet0/8 proxy dns
set dns server-select domain odessa.local outgoing-interface tunnel.1 primary-server 192.168.4.10 secondary-server 192.168.4.11
set dns server-select domain * outgoing-interface ethernet0/9 primary-server 207.164.234.129 secondary-server 207.164.234.193 tertiary-server 207.164.234.129 failover

Eth0/8 is my local lan (10.35.1.0/24)
tunnel.1 is the tunnel I have with my workplace

I'm able to reach all resource on that work lan (192.168.4.0/24)

If I do : nslookup whatever.odessa.local 192.168.4.10,  it work, I get the result..

but if I do only : nslookup whatever.odessa.local, i get timeout..

I had looked the dns log ..

I see that:

2014-02-02 09:58:33   info   DNS request "odessadc01.odessa.local" from 10.35.1.10/64824 is forwarded to server 192.168.4.11/53
2014-02-02 09:58:30   info   DNS request "odessadc01.odessa.local" from 10.35.1.10/64825 is forwarded to server 192.168.4.10/53

So it seem the ssg want to send the request to the right server, but it doesnt..

please, i need help :S

Thanks
