Almost certainly :-) Even quite big NAT boxes will get indigestion if you put a lot of DNS traffic through them. In general it's best to keep stateful middleboxes away from DNS servers. In your case you are probably better off either setting up a DMZ at home (if they will give you multiple IP addresses) or get a colo box for high volume DNS query traffic.
