thank you, I tried it and success. Thank you so much
I'm using TP-R470T+ (with 12 Mbps cable modem as wan1 and 6 Mbps ADSL+ as wan2) and I have no problem configuring certain IP to specific WAN (got the guide from http://www.tp-link.com/en/faq-530.html) . Problem is; I have VPN connection (I use hamachi; www.logmein.com) and I want my VPN to use wan2 because apparently the connection to my office (and other VPN clients) is faster because other VPN member also use the same ISP (the ADSL+ isp).
Question: How to configure the router to separate VPN connection with other connection from the same IP ?
Looking forward to hearing from you guys...
