Solved: If DD WRT VPN doesn't connect after rebooting since this weekend

[tedreddy 0]

I rebooted one of my VPN routers today (Monday)  and it didn't connect.  Looking at the VPN status page it was showing a date from 1970, and an error message read certificate was in the future.   Searched the DD WRT forum for NTP Not Working, and found a suggestion to erase the xxx.pool.ntp.org address on the basic setup page.  DD WRT will use a default NTP address if the entry is empty.  After Apply Settings, DD WRT picked up the time and my VPN was working again.  I have a pretty recent build, if your build is older it might not have this problem.
