Today I issued the following command into my cousin's company's pix 501 through the PDM:
static (inside,outside) 220.127.116.11 192.168.0.25 netmask 255.255.255.255 0 0
After I did that the firewall stopped passing traffic altogether. Now I can't even VPN into it to reverse the change. I'm thinking the only way is to power down and up the firewall since I didn't get a chance to save to flash.
I was just trying to do some port forwarding for a web application.
