Widows is using the same ports.
In the logs on pf sense, I can see 4500 and 500 being passed to the windows box.
Basically, what this comes down to, can the pf sense pass-through IPSEC/L2PT vpn requests.
It seems it will do IPSEC/L2PT no issue at all, but when i want to use a pre-shared key, it dies.
Its possible this could be because of NAT-T?
I am not very good at this stuff, but I am trying.
Thanks for your quick reply.
