Question : Cisco 871 router; telnet

I have a Cisco 871W Router; default firewall enabled via SDM Express; unable to get a ping response or telnet to router from outside; with firewall disabled no problem; I am familiar with CLI but do not know much about firewall configuration; a list of command line entries to allow telnet and ping response from outside would be great.

Answer : Cisco 871 router; telnet

No and theres probably not any app that can do it either as apple does not allow access to those API's. I believe the ipad can show slideshows when it's locked but thats the closet you're gonna get, at least for now.
