I have met a problem with SA540's optional port. I've set it to DMZ mode, and enable it to have an outbound traffic. The problem is: each time I reboot the SA540, the optional port has trouble, all traffic is blocked, I can't ping to anywhere. The only thing I can do is to go to the web UI, and change the port mode to WAN mode, apply, and then rechange it back to DMZ mode, then it works as usual. Is it a bug? Will it be resolve in the next version of IOS? Any help will be appreciated.
There are problems with the optional port being DMZ in the 1.0.39 firmware. A new version should be due out soon that should fix that problem.
