Is UDP port 2067 involved in DLSW? Or just TCP ports 2065, 2067, 1981,1982, and 1983. Also, does NTP use the port for time, or just the NTP port?

I have found useful info on DLSW TCP ports in the archives, but I did
not see anything about UDP port 2067, which is being stopped by my
firewall access-list which permits DLSW ports. DLSW is working fine, so
what application or routing protocol uses UDP port 2067? I believe it
is DLSW because of the source and destination IP addresses involved (two
DLSW remote-peer addresses).

Also, I notice there is a port for time (TCP 37) as well as a port for
NTP (UDP 123). What ports do I need to let through for NTP to work
between routers?

Thanks in advance,
Thomas Larus
