Remove the IP address configuration from the main host router and set up the Static IP address ON the DNS using it's web page. Just leave the DNS set to DHCP on the main host router so it gets an IP address. Use that dynamic IP address it gets to connect to the DNS's web page. Once there, go in and set a Static IP address ON the DNS. Static IP address should be 192.168.1.34, Gateway will be the IP address of your main host router, so if it's 192.168.1.254, use that. Subnet Mask will be the same as what the Main Host router uses, I presume 255.255.255.0
