RAP in split-tunnel mode and DNS traffic


I need to have all DNS queries go to the internal corporate network. With the RAP in split-tunnel mode all DNS queries are going to the RAP locations ISP DNS.

Any ideas?

Three things

1. Make sure the client is only getting the internal DNS server in the DHCP option
2. Make sure, in the AP system profile, the "Corporate DNS Domain" NOTHING is set for that AP-group (that is most likely your problem). If that is set, DNS traffic will ONLY be tunneled back to corporate if a lookup's domain matches that parameter
3. Make sure, if you have a firewall policy in that role for DNS traffic, that it is just set for "Permit"
