How to bypass Port 139 for logging into a AD DC

[brian]

I'm trying to log in a client over the WAN, but my
router's ACLs are blocking 139. I can't change this ACL
due to security so is there any way I can get the client
to log in without using Port 139?

Things I've tried so far include:
Disable NetBIOS over TCP
Create a LMHOST entry

Yoo,

LMHOST is only involved for name resolution speeds up, it has no implication
for transport

Keep in mind the following :
NetBios is a session-layer protocol that has not network layer for routing
it.
Therefore, in order to make NetBios routable, it is transported over TCP/IP.
Guess which TCP port it uses ... 139 is one of them.
Blocking 139 means blocking Microsoft
