Router: ASUS 520GU Currently running "Tomato v1.27.8744 vpn3.6 ND USB VPN" that was downloaded from "https://sourceforge.net/projects/tomatousb/files/K24/" more than one year ago. I wanted to upgrade, could some one help to point out which version that I could choose? For usage, besides as an router, I also want to have USB support(printer server), VPN, and install asterisk on it. I also hoping that my current settings will be there once I did upgrade? or I have to export and import? or Need complete setup from scratch? Thanks!
