pix, PAT and SNTP

Is there anything special I have to do to allow a windows 2000 server using w32 time service (SNTP) to access a time server through the outside interface of a PIX? I would like to accomplish this using only PAT on the outside interface's IP address, but I'm not sure if PAT will stay loyal to the UDP port 123 restriction (especially if we're running PAT on the outside interface's IP address).

Are there any access lists that have to be set up? My understanding is that the server on the inside will always initiate contact with the outside server and wait for a response. So the inbound packet should always be a response to a packet instead of really being an outside source trying to contact a server on the inside.

Thanks

Pat

Re: pix, PAT and SNTP
