Point a retail 12.0.7.68275 client at your server. This page is deliberately concrete: it separates what you change on the server from what you change in the client.
You do not edit game data. You only:
WoW.exe.WTF/Config.wtf: SET portal "YOUR_SERVER_IP".That’s it. Everything else is server-side.
In bnetserver.conf:
; The address the CLIENT will reach (public IP or LAN IP of the server)
LoginREST.ExternalAddress = YOUR_SERVER_IP
LoginREST.LocalAddress = YOUR_SERVER_IP
LoginREST.Port = 8081
In the auth database, the realm the client sees comes from the realmlist
table (not a realmlist.wtf):
UPDATE realmlist
SET address = 'YOUR_SERVER_IP', localAddress = 'YOUR_SERVER_IP', port = 8085
WHERE id = 1;
Make sure these ports are open to the client: 8081 (REST login), 1119 (bnet), 8085 (world).
Create an account (worldserver console):
account create myname mypassword
account set gmlevel myname 3 -1
The client build must equal the server’s world-DB build. Use BNetInstaller to fetch/keep build 12.0.7.68275, or a full retail install pinned to it. A mismatched build will fail at login every time.
Copy Arctium WoW Client Launcher.exe into the client folder, right next to
WoW.exe. Arctium patches the running client in memory so it:
No game file is permanently modified.
Open WTF/Config.wtf in the client folder and add (or edit):
SET portal "YOUR_SERVER_IP"
Optional, if you want to force locale / skip the launcher update check:
SET textLocale "enUS"
SET audioLocale "enUS"
portalis the only required client edit. It tells the client which Battle.net host to talk to — yourbnetserver.
Run Arctium, not Battle.net.exe. It starts the patched client and shows the
Battle.net login screen pointed at your server.
account create.Modern retail login goes through the HTTP REST dev-certificate path (port
8081), not the old realmlist.wtf. 95% of stuck logins are one of these:
| Symptom | Cause | Fix |
|---|---|---|
| Stuck “Connecting” / “Authenticating” | REST endpoint 8081 unreachable, or portal wrong |
Verify LoginREST.ExternalAddress + port 8081 open; check SET portal |
| “Version mismatch” / bounced at login | Client build ≠ 68275 | Reinstall/repin the client to 68275 |
| Realm list empty | realmlist.address wrong or worldserver (8085) down |
Fix the realmlist row; confirm 8085 is listening |
| Certificate/handshake error | Arctium not used, or cert not trusted | Always launch via Arctium |
| In game, but a character has no quests | Data/quest-chain gap | See FIXES.md |
