How does the official Diablo II LoD client find the IP/Port of the MCP server? I've tried packet logging it and could find no instance of SID_LOGONREALMEX being sent or received.
I'm working on a Battle.net proxy server and trying to add Diablo support, but I suspect the client is trying to connect to the actual server rather than my proxy (the game freezes up and there are no records of a connection request), so I need to find where the IP is specified.
The game receives the MCP server's info from SID_LOGONREALMEX, it's the 5th DWORD. If you replace it with your proxy server's IP and send that to the client, it should work fine.
I still can't find it. Searches for "3E" came up with nothing in the packet logs.
Here's what I got. FTP stuff was edited out along with sensitive information.

and you're not connecting to open battle.net?
Correct. Open Battle.net works without error.
Any chance it's in bnserver-d2dv.ini?

Just did a packet log. 0x3E is sent by the game right after 0x40 (queryrealms2) is received. It looks like you're not sending or receiving that either.
After you receive 0x3A, you should send 0x40 and 0x3E. For some reason, you aren't.
Editing bnserver-D2DV.ini as suggested to include my IP address did not work. (I'm certain this part was done correctly because the changes show up as desired in bncache.dat)
I'm going to set up a packet logger for a second opinion to my DebugOutput function and also to see it working correctly on the normal server. :-/
The realm server to connect to is sent in 3E. I'm 100% sure of that. I've already done what you're doing, and I got it to work fine.
nm fixed
You have to request a realm list to get their IP/port/name
He's not the one sending the request, he's making a proxy system for the game to go through. The game's the one not sending the realm list, not him.

Reading > me. Made an assumption that this was another one of those threads, if you get what I mean.
Of course, especially since it's in the bot dev forum.
