mnathani: make sure your prefixlen is correct, I had similar issues where I had set a 48 as 64 mnathani: One thought - set fe80::2/64 as the primary address instead of as an alias? I'm wondering if, yes, traffic for fe80::2 is arriving at your box and responding, but if connections from your box are using the automatic link-local address as source and that wouldn't be routed as necessary. (But I'm no expert on FreeBSD's rc.conf, their syntax/options are changing so damn frequently that I just stop touching my own once it's working right and never, ever touch it again. Also I don't have FreeBSD @ ARP) (Again, all completely hypothetical. Your /48 config seems to match how I have a Debian box configured so it seems like it should work otherwise) Thanks brycec : removing the alias portion of my FE80::2 address made it work. w00t, I guessed right! I probably spent atleast 45 minutes trying to get the syntax right last night was even considering switching to ubuntu on this VPS Lol, ouch
