I have a wireless access point and firewall combo that protects my meager home network from the Internet. Yesterday, I disabled the wireless interface (since I wasn't using it) and all seemed well.

My caution was rewarded with inconvenience. Even though the firewall settings displayed no changes, port translation was affected. Since the disabling the wireless connection was the only difference, I heeded my little voice and turned it back on. I changed the port number for the source, saved the settings and retried. All was well. I changed it back on a hunch; still working.

Just to make sure, disabled the wireless interface, again changed the port numbers for the translation–no workie. I had the wrong firmware installed on my firewall–Rev B vs. Rev A. Downloaded new firmware, installed, reset, all fixed.

Update:  I'm reposting this from work to make sure all is fine remotely. –Now twice–
