Odd router issue

[TechnoPro]

My client has a DSL modem / router combo at his business. He had previously had it configured it to forward a certain port for a video surveilance appliance. I needed to forward 2 other ports for PcAnywhere. Worked fine as verified by remote users. Power was lost in the store and the port forwarding entries I put in were lost, but the video surveilance entry was still there.

How can a router selectively lose a setting like that? On the web inteface, all I saw was the "Apply Settings" button. There was no secondary "Save settings" button or anything like that.

Any ideas?

What type of router is it? I believe his entries for security were far more superior than your little remote desktop app so the router decided to keep those.

If it was smart enough, it could have "last known good configuration" settings/ backup files.

Other than that....i'd guess corrupt memory/storage...

Thanks for your input.

The router type escapes me.

Both his and my entries were for simple port forwarding, so there was no issue of prioroty or superiority.

My solution was to keep the router plugged into the UPS.

Well, keeping the router on the UPS would be a good idea in any case. A network is somewhat useless if the central point goes down.

Hardware is flaky. 🙂 Things like this happen. Maybe the first setting was properly written to the NVRAM but the new ones weren't. Maybe it needed a "soft-reboot" after applying the settings in order to actually save them to NVRAM and not just volatile memory.

I got a bit of a condescending vibe from the post from kfranc9, aside from the probably lack of understanding it shows. No "security entries" were mentioned. And I've never heard PCAnywhere called a "little remote desktop app". Plus routers don't "decide" what settings are better.

That's what it sounds like to me... if it's a Cisco router, it sounds like the settings for the video surveilance appliance were saved to the startup config (NVRAM), but the forwarding for the PCAnywhere was only in the running config, and not the startup config.

After speaking with the client and walking him through the port-forwarding settings, he did come across some sort of "Save to ROM" function. My fault for not being more thorough when onsite.

I felt the same vibe from kfranc9. Not a very happy camper it would seem...
