Hi,

1. I suppose that the problem is in your PREROUTING rules

Chain PREROUTING (policy ACCEPT)
target     prot opt source               destination
DNAT       tcp  --  anywhere             anywhere            tcp dpt:search to:10.0.20.10:22
DNAT       tcp  --  anywhere             anywhere            tcp dpt:domain to:10.0.20.10:53

DNAT       tcp  --  anywhere             anywhere            tcp dpt:6020 to:10.0.60.20:22
DNAT       tcp  --  anywhere             anywhere            tcp dpt:6040 to:10.0.60.40:22
DNAT       tcp  --  anywhere             anywhere            tcp dpt:6080 to:10.0.60.80:22
DNAT       tcp  --  anywhere             anywhere            tcp dpt:8010 to:10.0.80.10:22

Can you please explain what do these rules mean? Especially

DNAT       udp  --  anywhere             anywhere            udp dpt:domain to:10.0.20.10:53

Try to remove all these rules.

2. If it doesn't help can you please answer some questions?
Is it possible to ping yahoo.com from HN?
Can you please provide us with the tcpdump output when you ping yahoo.com from HN?
Can you please use for example 4.2.2.4 as a nameserver on HN and inside VPS?

Thank You!
