Hi,
I have UTM 9.5 running with two Routers (each DSL, native IPv4, no native IPv6). One has static IPv4, the other dynamic IPv4. I want to set up a IPv6 tunnel with the dynamic Router.
Recently I aquired an IPv6 tunnel from tunnelbroker.net and I'm struggeling with the correct setup.
What I get from tunnelbroker.net:
My tunnel endpoint is 2001:xxxx:xxxA:xxxx::1
My router endpoint is 2001:xxxx:xxxA:xxxx::2
Designated /64 is 2001:xxxx:xxxB:xxxx::/64
I've set the address on the UTM-Interface [Interfaces & Routing > Interfaces] to 2001:xxxx:xxxB:xxxx::1 (first address in my designated /64). And I've checked the "IPv6 Default Gateway" and set the Gateway address to FD00::xxxx:xxxx:xxxx:xxxx, which is the address from my router.
Under [Interfaces & Routing > IPv6] it says "Native over Dynamic: 2001:xxxx:xxxB:xxxx::1, Subnet: 2001:xxxx:xxxB:xxxx::/64" (which seems to be correct)
When I check with http://whatip.me/ it says "your ipv6 is 2001:xxxx:xxxB:xxxx::1" which makes sense, since I use Web Protection from UTM (therefor UTM is Proxy and no website sees my clients IPv6).
Now, what puzzles me is this:
Every computer in my network gets an IPv6 with the following prefix: 2001:xxxx:xxxC:xxxx::/64 (notice the "C", not "B" as I would expect)
Where is this coming from? I would think that my clients should get anything from within my assigned Prefix... Seems wrong to me. Can someone please elaborate on this?
Thank you
Martin
