Are UDP 500, 1701 and 4500 ports being blocked -- VPN ports ??

I recently set up a VPN back into my network (for use on public wi-fi, keep they prying eyes away). 

Everything was working and now it is not.  I checked the access to the port via the internet and they are now closed.

Is VZ blocking UDP 500, 1701 and 4500 now.

#1 Is the computer that you are forwarding to a Static IP?

#2 Is that Static IP outside of the DHCP Range of the router?

#3 If you don't know what the DHCP Range of the router is, it would help to know the brand and model of your router.

Yes, the server on the inside is a static IP.

#2 Is that Static IP outside of the DHCP Range of the router?

Yes, the static iP is  well above my 4 devices that get their normal dhcp address
i put the starting VPN DHCP address well above my static IP  and yet below where the set boxes start using IPs.

#3 If you don't know what the DHCP Range of the router is, it would help to know the brand and model of your router.

I believe the router is the standard VZ issue ActionTek MIR some model, can dig it up when i get home.

Things to note: 

All my other port forwards (ssh, http, https) are still working, they terminate on the same host as the VPN.

DNS is up-to-date as i can still access the box from the internet  (I am using dyndns updater).

I nmapped from the internet to my host on ports 500, 1701 and 4500 and they are close, where my other port forward ports are open.

Short answer is no. Verizon only blocks outbound port 25 to combat spam.
