Hi All,

Our VPN stopped working a week ago, and I got it working by allowing all UDP traffic in "Internal networks to Zentyal".

A week ago I did make some changes adding machines to our local domain, and I turned off a few Samba shares. I can't make sense of why the "Internal Networks to Zentyal" firewall rule allowing UDP would fix the VPN connections...

Any direction / explanations welcome!

Owen.

I since restricted the UDP from internal networks to allow any source port, but restrict it to the destination VPN udp port.

I still don't understand what changed to break / require this additional firewall rule to work. No updates were run!
