My colleague with the Cisco router is now having problems with his Vonage service. They are telling him he needs to set up port forwarding for a range of ports (10000-20000) for it to work properly.
I have successfully used the following command for his SMTP and FTP traffic:
ip nat inside source static tcp 192.168.1.112 25 64.00.00.00 25 extendable
Can this same command be used for port ranges, as well? Could someone clue me in on how to do this?
Thanks in advance!
