So very glad you're around! Looks like we have very similar set ups, I too am using eKeypad.
Would you be willing to set up a DNAT port forward to the secure port on your M1XEP and see if you can get consistent connections? Mine work about 10% of the time.
Also, for the VPN, I had mine configured that way for a while but I got tired of having to dial the VPN manually.
On a somewhat related note, have you tried getting VPN on Demand to work? I can get it to dial the connection on demand but it prompts for password every time, instead of using cert based auth.
