Smoothwall error "Unable to run command" fix

If you are running Smoothwall express 3.0, and you are having problems with the port forwarding section not working, and getting the "Unable to run command" error, we found a solution to some of your needs:

If you are adding comments to any of the port forwarding rules, delete them, and restart smoothwall. This allowed port forwarding to work again and got rid of the "Unable to run command" error.

Hope this helps you. If you were not adding comments to port forwarding rules, it could be an issue with Snort, the intrusion detection system that comes with Smoothwall (or another issue). See "Unable to run command" thread on the smoothwall forums.
