[Solved]DHCP Client not getting DNS Server

jdmoore0883
Hey Guys!

So I have my Sophos GW configured to be a DHCP server. The DHCP Client is getting an IP address and getting the proper gateway, but it isn't getting the DNS server. When I try to run any kind of nslookup, it fails because there are no DNS servers configured. When I run nslookup and point it to my Sophos GW, it resolves instantly. So the DNS is working fine, but the DHCP Client is not getting it...

In the DHCP setting I have DNS Server 1 pointing to the internal IP (same IP i used for nslookup). No DNS 2. GW is the same internal IP (and this works).

Any ideas on what to check next?

Thanks!

    I had this issue when the DHCP server was running on a vlan'd and aggregated trunked connection, client's simply wouldn't get an assignment, everything else was fine.  Removing the link aggregation resolved my issue.  My UTM 9 now works fine with 4 dhcp servers, one on each vlan on single port trunk to the switch.
