Re: M0n0wall and multiple interfaces

said by mcnet:

yes that should work for /64 sub division of /48
Ok, I'll try that when I get back in front of a console tonight.

said by mcnet:

because it's off by ipv6 equiv of an octet... 16-et? hexadigit? hexet?

2001:ded:bef5:dc6::78:eeee/96
2001:ded:bef5:dc6::10:eeee/96

should be:
2001:ded:bef5:dc6::1:78:eeee/96
2001:ded:bef5:dc6::2:10:eeee/96
(one more 4-space to left)

long format /96 S = network/subnet H = host
SSSS:SSSS:SSSS:SSSS:SSSS:SSSS:HHHH:HHHH
so have have 2nd subnet routable it should be difference in 3rd from right group of 4 hex digits. right? i think so...
Hmmm...

Expanded, out the address (2001:ded:bef5:dc6::78:eeee) should be:

2001:0ded:bef5:0dc6:0000:0000:0078:eeee

So at 96 bits... (add add add)...

2001:0ded:bef5:0dc6:0000:0000:0078:eeee

So for the :0078: part to make the difference, I should have used /104? That doesn't sound right, but I've been wrong before...

that would be a /112 i believe (each 4 symbols = 16 bits, 128-16=112)

Doh, I think I grok...

So given the address of 2001:0ded:bef5:0dc6:0000:0000:0078:eeee, /112 would make 2001:0ded:bef5:0dc6:0000:0000:0078 the 'subnet', with the 0078 part the entry that changes to identify the different subnets and the eeee part for each machine.

BTW, I tried the /48 approach and it's working, thanks for the pointer. Now to try and figure out if a DHCPv6 server and DHCPv4 can coexist on the same network without banging heads and get bind set up to deal with ip6 as well.

Thank you for the help and info so far, it is appreciated!
