How do I open UDP port 123 thru the Cisco 1941 router
I am new in cisco, and I have one question about open UDP port 123. I have a 1941 router. I need to open UDP port 123 for 64.147.116.229 to one of my internal server (IP 192.168.0.1). Do I use the following? Thank you in advance.
permit udp 64.147.116.229 192.168.0.1 eq 123
permit udp 64.147.116.229 192.168.0.1 eq 123

ic, thank you for your help mrmozaffari. for permit udp 64.147.116.229 192.168.0.1 eq 123, should the external Ip go first or internal ip? I need to establish a 2 way communication.
