Hey what wrong with Hong Kong. I don't believe you will have a lot of ports scan or dictionary attacks from Hong Kong. China yes may be. But Come on.. You will be more likely to get port scan from a network like ev1 which from Hong Kong. Or at least may be 5 times as much.
If you read the statistic, most hacks attempts or scam attempts are from China, Africa(not a lot of hack attempts), Russia, USA <---yes my friend USA too, you really won't see a lot from Vietnam (their broadband go down every afternoon for a few hrs and bw price is rocket high), Thailand (they are paying like close to $400 -1000 USD per mb so you think they will use it to port scan you ?)

(here we go again) Maybe an overly shotgun approach for your tastes, but I personally firewall off all IP blocks from APNIC (the Asian-Pacific RIR) delegated to the southeast Asian countries (China, Korea, Vietnam, Thailand, Laos, Hong Kong -- yes, I know it is not a country). Over 90% of my port scans, my dictionary attacks and my problems seem to come from there. If you take that approach, definitely don't block all the aggregate APNIC ranges. That would exclude quite a few Australians and New Zealanders. There are plenty of lists available online reliably of the blocks delegated by country, with a specific focus on that region. It is not an uncommon practise among sysadmins. -- Alex Balashov Evariste Systems Web : http://www.evaristesys.com/ Tel : (+1) (678) 954-0670 Direct : (+1) (678) 954-0671 Mobile : (+1) (706) 338-8599 _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- AstriCon 2008 - September 22 - 25 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-biz mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-biz _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- AstriCon 2008 - September 22 - 25 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-biz mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-biz
