[Resolved]: OpenVPN GUI client settings issue I am using TomatoVPN 1.25 on WRT54G version 4 hardware. I think this iteration is really good, but I ran into two small issues. Issue One: I was able to successfully setup VPN client to a remote site. The issue comes when I try to replace the client certificate and client key with newer ones in the GUI. It keeps giving me "Invalid address" error when I hit save button. When I refresh the screen, I still have the current client certificate and key. So I end up not able to replace my client certificate and key. Has anyone experience the same issue? I think I may be able to get around this using the command line option in terminal to replace client certificate and key. Can someone please show me how? Issue Two: I also setup the VPN server, but it refuse to start up. I did the same on a different hardware, Buffalo WHR-HP-G54, and it works fine. So may be this is Linksys WRT54G/GS/GL specific. Any enlightenment on how to troubleshoot on this is greatly appreciated. Thanks in advance.
