I'm having an issue with 1-to-1 NAT and the RV082. I currently have 1 machine entered under 1-to-1 NAT that works fine. I have another device (a NAS) that will work for a short time when its internal address is mapped to an external IP through 1-to-1 NAT. After a period of time (I haven't been able to exactly time it), it will cease to work (meaning I can no longer access it from the outside). I never lose the ability to access it internally. I thought that maybe it was an ISP issue, but if I wipe out the entry in the RV082, save changes, re-enter it, save settings, it will begin to work again. The other machine is not affected.
