Hi,
I also had the same Problem. But I don't found a solution.
There are a Starcraft How-To but this don't work.
I think the beste solution is to get officals IP Addresses and the
only forward. (Maybe you can get a few IPv6 Addresses, and then Play
with ipv6 on battle.net (But I don't know whether Battle.Net support
ipv6)
I attached a E-Mail which I get from Battle.Net

Hello,
Unfortunately there is no way to change or forward the port for Starcraft. I suggest you contact your router manufacturer for further assistance. I do apologize for any inconvenience.

Subject: Re: Battle.Net Connecting Problems
Hello,
We can play Starcraft online on Battle.Net but only if we don't open a game on the LAN-Network.(We have to join an game, but we cannnot create a Game) The Question is now can I redirect the port 6112 to another port for example to 60112. (I know how to redirect this ports, but I don't know wheather the Battle.Net will then also connect to this port.)
In other words: When a Client will connect to a server to play a game, it usually connect to the Server-IP with tcp/udp port 6112. Can I tell Battle.Net to use another Port, so that the Client will connect to the Port 60112 and not to 6112?.
Or how do the Clients know to which ports they should connect to the other Clients do they always use the port 6112?
I need this because each Client is talking to the other Clients an when
2 Clients are hide behind one offizial IP-Address, I've to seperate the Connections, but I can only do that, when the incoming data is send to another Port.
Here is a Diagramm what I mean:
|---------------------|
| LAN | |---------------|
| | |--------| Client-3 |
| |----------| | | |---------------|
| | Client-1 | | |
| |----------| |-----------|DNAT | |------------|
| SNAT| Router |--------... WAN ... ---- |Battle.Net |
| |-----------| |------------|
| |----------| | |
| | Client-2 | | | |-----------|
| |----------| | |-------|Client-4 |
| | |-----------|
|---------------------|
Client-1 will open a Server on the Battle.Net Server. (listen udp/tcp6112 ) and connect to Router(->forwarded to Client-2), Client-3,Client-4
Client-2 will connect to the Router(->forwared to Client-1), Client-3,Client-4 (dest: Router:6112 udp/tcp)
Client-3 will connect to the Router(->forwared to Client-1),Router(->forwared to Client-2), Client-4 (udp/tcp 6112)
Client-4 will connect to the Router(->forwared to Client-1),Router(->forwared to Client-2), Client-3 (udp/tcp 6112)

> Most proxy servers, firewalls, and other Internet connection sharing methods can restrict port access. Your configuration may be restricting packets from "unknown sources". In this case an "unknown source" would be defined as any IP address that you have not initiated the contact with. Once you contact the IP address, your proxy and/or firewall considers it "safe", or a "known source", since you initiated the contact. When you create a game on Battle.net, other users need to be able to contact you in order to join. In other words, they need to be able to initiate the contact. This becomes the real problem if your connection is restricting them from contacting you.
