I just solved the issue.
The solutions is: modify /etc/sysconfig/SuSEfirewall2 as the /usr/
share/doc/packages/SuSEfirewall2/EXAMPLES sample 2. Small home
network.
The sample settings are:
FW_DEV_EXT="dsl0"
FW_DEV_INT="eth0"
FW_ROUTE="yes"
FW_MASQUERADE="yes"
FW_MASQ_NETS="192.168.10.0/24"

after I reboot the suse(should I restart sth instead of reboot?) the
ssh works good from windows side.
I know it is a little risk, but, I just want the ssh connection
working for a couple of hours, then I will change all settings back.

Thank you guys for your time.
