Feels like I'm finally close to getting this all working at the same time.
I'm still missing the last piece -- ping6 from LAN to 'NET
(1) router
ip -6 addr show

ON desktop, I
*CAN* ping6
@desktop
2600:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:23e1
fd81:17:15::7
@router, INT
2600:yyyy:yyyy:yyyy::1
fd81:17:15::128
@router, EXT
2600:yyyy:yyyy:zzzz::53
can *NOT* ping6
@desktop
fe80::6d9:xxxx:xxxx:23e1
@router, INT
fe80::e310:84ed:bda1:a331
@router, EXT
fe80::e310:84ed:bda1:a330
google.com
2607:f8b0:4008:803::200e
ON router, I
*CAN* ping6
@desktop
2600:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:23e1
fd81:17:15::7
@router, INT
2600:yyyy:yyyy:yyyy::1
fd81:17:15::128
@router, EXT
2600:yyyy:yyyy:zzzz::53
and,
can *NOT* ping6
@desktop
fe80::6d9:xxxx:xxxx:23e1
@router, INT
fe80::e310:84ed:bda1:a331
@router, EXT
fe80::e310:84ed:bda1:a330
BUT, I
*CAN* ping6
google.com
2607:f8b0:4008:803::200e
I.e., ping6
router -> google.com OK
dekstop -> google.com FAIL
Any hints about what the missing piece is?
Is it a route, rule, policy or other Shorewall config that I need?
Thanks,
Thad
