I also use Cisco routers but they are enterprise models rather than SOHO models. Started
with a 2801, then a 2911, currently using a 4331. I?ve never had problem with IPv6 with
them.
I have the new software installed and am ready to connect. My IPv6 address is
2601:281:c180:5000:1:a000:9:fc01.

I can't wait to try it out..... except that I bought a new Cisco small business
router (RV340W) and this has introduced a whole load of IPv6 woes.
LAN -> WAN initiated calls work fine...... except that windows hosts eventually forget
the link-level address of the router and the router itself throws up something worrying in
its logs about being unable to advertise the router address.
WAN -> LAN initiated calls don't work at all. They don't even get as far as
tickling an access rule's logging setting.
I'm really annoyed that changing any firewall rules (v4 or v6) causes all stateful
connectivity to be forgotten and everything is dropped. Even Draytek Vigors didn't do
this unless the rule change was pertinent to particular connections.
What really really annoys me is some linux daemons (DHCP server) being terminated and
restarted every 15 minutes or so.... almost as though it's a quick a dirty fix to some
sort of bug they couldn't figure out.
Sorry for the rant. I just remember when Cisco and quality appeared to be two different
spellings for the same concept. I'm sorely tempted to roll my own. After all, who
needs a UI?!?

The code is checked in now, subversion rev 570. Be sure to read doc/config.txt.

Hi Paul,
This is great news and will allow me to ditch some troublesome bits of NAT.
Surely dyndns.org is less of an issue for IPv6 if your ISP has allotted you a permanent
/64 prefix?

Why? Because I felt like it and it wasn't too hard.
I have a PyDECnet version that can handle not just IPv4 but also IPv6. It's on node
PYTHON right now and on the map server 28NH (at akdesign.dyndns.org). This applies both
to the web interface and also to the various IP-based datalink protocols. I've tested
Multinet, GRE, Ethernet (UDP bridge) and DDCMP.
If anyone is interested in using this with PYTHON, let me know.
Unfortunately dyndns.org doesn't support IPv6 records well; I can enter one manually
but it disappears after a while for reasons I do not understand. It's there now. You
can access the mapper's web page (akdesign.dyndns.org:8080) that way if you like.
