DrayTek Frustration

I’m having some problems setting up my new DrayTek 2830. The problem is my old Billion router was on its way out as it kept dropping its connection. Now the Billion router would talk to a Cisco router via rip. The Cisco router routes between 192.168.2.0 to 192.168.10, 20 and 30 subnets. This all worked very well for routing between the VLANs. Each subnet (10, 20 and 30) would use the Billion router (192.168.2.1) for DNS.

Since the draytek went in this no longer works. Each subnets DHCP pool had to be changed to use 8.8.8.8 for DNS to get the internet working. So I can’t understand why the draytek can’t handle the DNS requests from the Cisco router for the 3 subnets, also I can ping any device on any subnet except the drayteks IP of 192.168.2.1 all seems to fail. To be clear both Cisco and draytek talk to each other via RIP v2 and both have the correct networks in there routing tables.

Any thoughts, thanks in advance
 
it might be that the RIP isn't good on it, have you static routes on each instead?
Which firmware on the 2830? Use 3.6.3 if possible, old firmware like 3.3.6.x is bad
Hmm, also check the syslog output and see if that gives any clues.
The last thing is, if you're getting DNS weirdness, please make sure firewall - dos defense - udp flood defense is turned off :)
