Thanks Ryan. I didn't think to try that because, as you said, the firmware it came with was the latest version already. Unfortunately, I was running out of time on my refund policy and didn't want to get stuck with a faulty device, so I sent it back before receiving your answer. I'm going to wait a firmware revision or two and purchase again at that time. Hopefully Cisco works these bugs out by then. It sure seems that the initial shipments of these to resellers is really buggy.
I've never had this high a percentage of bugs and quirks in a router before the RV042. It's definitely got a personality of its own. For example, if you're using VPN, restoring a settings backup to the router will not work with the VPN--you must manually reprogram your VPN settings in for it to work (this on my RV042, I don't know if it applies on the RV042G). Just reading across the problems here really indicates a lack of quality control on the small business line. I expect lower QC on a consumer line, not a business line (even if it is "small" business). Also on the RV042, email logs only seem to send out after you reboot the router a 2nd time after setting up, and occasionally emails will just STOP sending out. Rebooting the router will start the logs emailing out again. And the email logs on the RV042G appear to be completely broken, only sending out when you manually press the "Email Log Now" button. And lastly, the RV042G responds to pings at ports 0 and 1, and does not allow firewall access rules on port 0, so there's no way to stealth port 0. Fortunately, you can make an access rule to deny all traffic to port 1, which will stealth that port, keeping it from responding to ping requests. And port 443 is wide open to the outside world (presumably for VPN). You have to manually set access rules to block it off.
Fortunately, there are enough things to like about this router (VPN performance is by far the best in its price range) that sysadmins just need to learn the quirks and work around them.
