Some more info, hope it's helpful or you can tell me to stfu :)
I have other forwards where the inside host is a different port than the destination i.e. wan:3399 non standard port with an alias goes to an inside host at standard rdp 3389. These work.
Also non-standard port with an alias that are the same destination port wan and inside host.
What doesn't work is 2 non-standard port aliases that are different. wan:6060 alias to inside host 8080 alias.
That's all I got.
