Hi all, I just started with a company on Monday, and I've been asked to look at their network as they're running into some issues. We're currently running a linksys RV042 as our main router, with one main subnet for our corporate network. Recently, the purchasing manager decided that he wanted to install a VOIP phone system, so the purchase was made, system installed etc. The problem is that it was setup on a separate subnet, so we currently have no way to communicate with it other than through a server with two nics on it. The firmware on the current RV042 is from 2005 (v.18.104.22.168), so it's pretty old now. Apparently, in firmware v.22.214.171.124, the ability to add multiple subnets to the router was added (which I believe should solve our communication issue). I've never upgraded the firmware on a router before, so while I know it's easy to do, I want to make sure I understand the implications of doing so and have a backup plan in place in case something goes wrong. Does anyone have any helpful tips for getting the firmware updated? Are there any risks with jumping straight to the latest firmware version, or should it be done in sequence with each major release? Is there a process I should be following to backup the settings etc. before proceeding? Thanks for your help!
