Thanks for the reply !
Dear Shug,
Pls advise as below:
1. After putting 50000 to port start and 60000 to port end, do i need to put anyting for Destination port map? or the system will select a port for you btw 50000-60000?
2. I cant access to router configuration with http://192.168.1.1 in my office pc. Any other way could access to it?
3. You said make sure windows firewall is disabled. So I go to right click My Network Places, properties, double click Local area Connection status, properties, Internet Protocol (TCP/IP), then click advanced, then uncheck Internet connection firewall. Am I considered done?
Thanks in advanced
