Hello,
My bank, Citibank(Korea), uses Ahnlab online security as their main security software.
In order to login the bank's website and do internet banking, customers must install Ahnlab security, an Active-X based security software.
Recently, I couldn't login Citibank's website because when the security software(or the Active-X) tries to connect to its update(or engine) server, it just can't, therefore, I can't use the internet banking.
I called up the bank's support and they connected me to the Ahnlap's support. The Ahnlab consultant tried to check my system through remote access and found out that two of their servers are blocked by Norton DNS which I don't even have on my computer. She said that it may be my ISP that is using Norton DNS on their server to protect its subscribers.
The consultant showed me the links that I can check their servers' availability from my end.
The following links indicate those two servers that are blocked by Norton DNS:

http://ahnlab.nefficient.co.kr/onetouch/patch/dntest/dntest.html
The following links indicate the rest of thier servers that are not blocked:

http://su.ahnlab.com/onetouch/patch/dntest/dntest.html
http://su2.ahnlab.com/onetouch/patch/dntest/dntest.html
http://su3.ahnlab.com/onetouch/patch/dntest/dntest.html
I can't ask my ISP to disable thier Norton product just becuase of me, so I asking some help from Norton by writing this post here in this forum.
Ahnlab is a very well known security company and laboratory in Korea. Their product is used in numerous websites such as banks, government agencies, major search engines and portals, popular game sites and etc.
I have no idea why Ahnlab's servers are blocked by Norton DNS but I would like them to be unlocked as soon as possible. I urgently need to use the internet banking.
If any of Norton staff is seeing this post, please unblock those servers.
Thank you
