Hello all,
New here and am trying to get this working for my test lab.
I have looked through all the posts I can find here relating to DNS and have followed the DNS Best Practise thread I found. However I still cannot get my servers behind the UTM to connect to the internet.
A little bit of background:
I have a ESXi setup and am running a Windows Server 2008 DC and the UTM 9 device as virtual servers. The DC is a DHCP and DNS server for the test domain and has a AD Integrated DNS zone. There is one NIC on the dc connected to a Vswitch that has no external connectivity.
The UTM has just 2 NIC's active for WAN and LAN. The WAN side is getting an address from my Cable router and after following the DNS Best Practise thread the UTM can ping, tracert and DNS lookup external sites no problem. I have used the OpenDNS servers in the forwarders tab.
On the DC the DNS forwarders are set to the UTM first and then the two OpenDNS servers. It can validate the UTM and does reslove the names of the OpenDNS servers but cannot validate them.
The little Network activity icon on the windows server shows that there is internet connectivity but I cannot resolve any DNS names or browse the web with IE or Firefox. I have set the UTM as the proxy and there is a rule in the UTM for Web Surfing from Internal to Any.
Can anyone suggest why I cannot browse the web from this server?
I have tried all I can now and hope someone can enlighten me as to where I have gone wrong.
Many thanks and sorry for the long post.
