IPv6 address pingable after first ping FROM it
[sk] Shadow Hawkins on Friday, 10 September 2010 09:49:07
Hello, I have a strange problem with OpenWRT and AICCU. My IPv6 address is not pingable from outside. But when I log in to my router and ping any IPv6 address from console, it begins to respond to pings from outside. I have fair amount of knowledge about networks, but I cannot explain this phenomenon. Anyone with the same problem and solution? Thanks! Tomas

See the FAQ, it has an item about connection trackers which exactly is this problem.
