Question:
What does "Ignore "Don't Fragment" setting in IPv4 header" in VPN connection page?

Answer:
Select this to fragment packets larger than the MTU (Maximum Transmission Unit) that have the “Don't Fragment” bit in the IP header turned on.
When you clear this the Zyxel Device drops packets larger than the MTU that have the “Don't Fragment” bit in the header turned on.
