When i try to ping my router i get the U caracter :
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 22.214.171.124, timeout is 2 seconds:
Success rate is 0 percent (0/5)
but i can access via telnet to this device.
Does someone know or explain this issue ? is this will cause problems to incoming /out trafic of this remote router ?
Thanks for your reply.
