Dear All, The RV042 route work fine with the pppoe (WAN1) connection with all internet stuff. Now we tried to config WAN2 to serve smtp, pop3 and some others web services under our network area. We config a static ip, gateway, dns to WAN2, set "Load Balance" and add related "Protocol Binding" at "System Management"-> "Dual Wan" tag. After saved and enable those config, client pc's still use WAN1 to connect to those services. Seem the RV042 can connect to the WAN2 gateway as no error log at "Log" tag. The firmware of the RV042 is 184.108.40.206-tm (Feb 13 2009), which seem the most update one from http://www.cisco.com/en/US/products/ps9925/index.html. Anyone had idea on this? Thank for helping.
