My RV042 is occasionally losing routes to specific IP addresses. Randomly, specific IP addresses become unreachable. Traceroute returns a destination unreachable message at hop #1 (the RV042). Oddly, other destinations in the same /24 subnet are still reachable. (example: a.b.c.243 might be unreachable but a.b.c.242 is fine). Rebooting the RV042 immediately restores connectivity. I have to stress that the unreachability problem begins at hop#1 (the RV042) and not the ISP. The destination hosts are our gear in colo, and I know for sure they are active and responding. RV042 is running the most current firmware (18.104.22.168-tm). Anyone else seen this?
