have a cisco 1841 that the old "can't find him anymore" computer guy set up years ago. runs like a champ. while back, i with the help of a wonderful user from here i did a port forward so an app on my phone could connect to one of the pc's on the network and get info from it. everything worked fine for weeks until last week out the blue. the app wont connect to the pc anymore, getting an "unable to connect to server" now. pc and software seem to be running fine but cant completely eliminate it as the issue.
but i want to eliminate the router as the issue. i did email and left messages for the old computer guy to help me originally and never heard back. he does have the login info and want to make sure he didn't log in and delete the forwarding info i had put in.
what is the commands to see the port forward config? is there a log of recent logins i can pull up? no one should have logged into it since the day i configured the port forward. Thanks much in advance.
