need some assistance with my cisco 1841. i have an app on my phone that needs to get info from a pc inside our network. very green on cisco ios but was able to config an entry that worked for a while, however im now learning i did not add the entry to the startup routine and low and behold the power went out and now the app is not connecting anymore.
here's what i did...got into the router,
typed "config t" to get into config mode
typed "ip nat inside source static tcp <inside IP address> 80 <public IP address> 80 extendable"
(used my internal static assigned to that pc, used the port number i assigned in the software im communicating with which is not 80, and my public external ip)
type "end" to exit config
then exited my telnet session. got on my phone and it worked perfectly for months. till a power outage caused the router to reboot.
im now realizing once i exited the config mode i think should have typed "copy run start" to add that line to my startup?
so is that line somewhere still in the router but not in effect obviously as i cant connect with my phone anymore? or can i do it exactly the same again but this time do the "copy run start", then exit my telnet?
how do i look to see if the command is still in there hidden somewhere?
