Bug ID: 44895
           Summary: League Of Legends: Unable to log in if behind OpenWRT
                    based router
           Product: Wine
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

I don't know how much this really depends on OpenWRT, but that's the way how I
can 100% reproduce this bug.

I run LoL with latest wine-staging. I installed using this script:
https://github.com/GloriousEggroll/leagueoflegends-linux

So far I always used AVM routers. Fritz!Box 5050 first and as my ISP now uses
Annex-J, I had to switch to a Fritz!Box 7270.

With these routers, I never had any problem with logging in from the League
client.

Now I wanted to try using a 100% open source router based on OpenWRT. As soon
as I do so, connection to the LoL login servers fails.

My brother was able to reproduce this problem on his PC and he also has Windows
installed. If he boots into Windows, login works. On Linux with Wine, login
doesn't work.

So this is a Wine problem "somehow" as it works on Windows, but it may also
have something to do with the router or network infrastructure as it works on
Wine if a proprietary router is used.

I can provide more info if required.
