hi,
all updaters change the ip of the login server otherwise u would use the ones within the client, the off onces from nc. probably the updater doesnt block anything at all ... so all u have to do should be:
1. open your updater and start lineage
2. stop at the loginscreen (press alt+enter for the window-mode)
3. open a commandline window
4. enter "netstat -b" in the commandline and check the entry with L2 -> ip login server
5. append the following lines to your hosts file
#l2 loginserver
<login server> l2authd.lineage2.com
<login server> l2testauthd.lineage2.com
<login server> l2patcher.lineage2.com
6. close lineage and the commandline
7. start lineage with the l2.exe ... et voila it should work!
remember when you want to use another server, uncomment the lines with an "#"
if this doesnt work the server maybe uses a different port. i dont know how to solve this except for an extra software. but how do l2-updaters solve this?
