Hi, CSamuels
Thank you for your reply. Yes, I understand the fact that the Port forwading is required for this case. However, initially, i just had no clues of what port numbers i should use to do this forwading.
Thank you for telling me the port number. But, if this is for ADSL Broadband connection, can i still use the advisable ports for PPPoE type of connection.
Also, another thing is that i was told to use the DMZ if i don't know a specific port to forward to the VPN router from the ADSL modem router. I was told that if i enabled the DMZ and set it the IP addr of VPN router and that would mean that we practically open up all the ports for external access. Is that true?
Nevertheless, i have already enabled the DMZ and its IP addr was set too but still didn't work. By that i meant that the VPN connection from both ends was established. Everything seemed to be working. I can tell that by looking into the log file from both ends. No problem at all. But wierdly, i could not access to a PC from either ends. I have already made sure that the NETBIOS is turned on for both.
(shaking head) i run out of ideas. Could you please help me out?
Thank you very much in advance.
