Hello everyone.
I am new to this list but I am in need of some help.
I have been running OpenBSD since 4.6 as my firewall and gateway with
much success (transitioned from FreeBSD) and it was working out great as
a light weight and secure OS for my Internet router and gateway.
One of the uses of this box is to route IPv6 for my local subnet out to
the Internet. It used to use a free tunnel service that worked great.
But I have since transitioned to the IPv6 that my ISP provides me
directly. This was a bit painful at first but I got it working with the
help of some 3rd party software not available in the ports collection
called Dibbler. This software is not perfect, but with the help of a
script I fleshed out myself i got it to do what I needed. The client
portion of that DHCPv6 program reaches out to the DHCPv6 server on my
ISP's network and obtains all the information I need. The only thing it
is currently able to do on it's own is plumb up the primary IPv6 address
it obtains from the ISP. But I still have to add the requisite default
route information. Also I have to then manually plumb up the delegated
IPv6 prefix assigned to my subnet (that I request) to my internal interface.
I then use rtadvd to advertise that route and allow for SLAAC to work on
my internal network to all IPv6 aware hosts.
This used to work just fine until I upgraded my router to 5.6 from 5.5.
After adding 'inet6 autoconf' to my hostname.if files, it appeared I got
my IPv6 functionality back.
However, while the box itself is back on IPv6 Internet, the subnet it
acts as a router for can no longer get onto the Internet.
After looking into it further it appears there is something wrong with
the routing table. There is no route for the subnet of the address I
manually add via ifconfig to the internal interface. I do not know how
to do this, nor was this previously necessary. The ifconfig command I
call to add the address specified the prefixlen 64 which *should* imply
the address is part of a /64 subnet where all other addresses within
that subnet should be reachable via the same interface the address is
plumbed up on.
When I do a route show or a netstat -nr I do not see such a route nor
have I been successful in figuring out how to call the route add command
to add such a route.
Thanks in advance.
