[squid-users] After enabling IPv6 squid no longer responds

[James Moe]

Hello,
  squid v4.8

  I have started transitioning our local network to IPv6.
  After adding v6 addresses to the server and hosts, and enabling an RA, squid
no longer delivers anything from its cache, or is exceedingly slow about it.
  I have reviewed the wiki. The one section that discusses this issue has a
solution only for v3.1 or earlier. Does it also apply to later versions?
  What am I missing?
