Question : NTP & Port Forwarding

I have Linksys BEFSR81 ver. 1 router.

I can't update my time. I click on the time at the right bottom of screen, get Date & Time Properties, go to Internet Time, click Update now, get "error occured...RPC server is unavailable", but I can surf the net, get email.

Tried forwarding port, Customized Application - NTP - 7051-7051 -TCP & UDP, 192.168.1.1, enabled, but still above error message.

Tried both Win XP Pro defaul servers: time.nist.gov and time.windows.com, err message on both.

What to do?

Answer : NTP & Port Forwarding

> Hmmm.... try also mapping port 123 to your workstation in the Linksys router.

Unnecessary - my firewall has no such mapping, and I can sync time just fine (time.windows.com).

If you install cygwin you can use tcptraceroute and hping which will reveal blocking of the ntp port, and which hop along the path is doing it...
