Allowing NTP on all interfaces

[insccisco]

Hi guys,

I have configured my 1841 router to be a Master NTP server.

This router has 5 VLANS and hosts coming from all those VLANs can successfully act as NTP clients to get the proper time from the 1841. However, on one of those VLANs, I have an access list applied and hosts on this VLAN can't talk to the NTP master (the 1841)

What do I need to allow on the ACL to allow hosts on this VLAN to use the 1841 as their master NTP?

NTP runs on UDP 123 so you'll have to open up that port.

Hope it helps.
