OpenSUSE Network :: Cannot Access Community Repos List

Having assorted problems accessing v11.3 update repositories. The issue appears to be either with IPv6 or my ancient 2Wire 1000SW router.

Last week, I replaced Ubuntu with openSUSE on this Dell laptop. When I couldn't access repositories initially, I turned off IPv6 in YaST, with no luck. Turning off IPv6 in Firefox did allow me to see opensuse.org and other otherwise unavailable sites.

I edited my primary/default repo list in YaST with IP addresses replacing DNS names with great success -- except for the non-OSS repo, which YaST couldn't find. Anyway, I had a successful update!

Now adding repos to the default set is the problem. When going to Add > Community Repositories, I get the "Unable to download list of repositories or no repositories defined" message. Trying to add Packman.unixheads.com either with named URL or with IP address doesn't work either (it was curious that when using the IP address, YaST still says it can't find Packman.unixheads.com).

When I read that Packman was converting all its servers to IPv6, just for grins I went back to YaST and Enabled IPv6 again. After a reboot, I tried adding Packman again. No luck, but suddenly editing the default openSUSE non-oss repo and entering the IP address WORKED!

One more data point: I tried using a few 1-click installations from the collection at opensuse-community.org. Most failed, but for some reason, I could add the NVIDIA repository!

While I think the simple solution is probably replacing the router I've had since 2004, I'd like to avoid that particular expense right now. I'll note that I never had a problem accessing (K)Ubuntu repositories.

I'm wondering if there's a zypper or YaST config file I can edit that might allow access to the Community Repo list (though the Packman experience is somewhat discouraging in that regard). Is there something weird going on with MirrorBrain too? Figuring out how to handle IPv6 might be relevant here too.
