AnyConnect 2.5.0217 Linux: no IPv6 default route to cscotun0
while testing AnyConnect Version 2.5.0217 we see the following issue with IPv6 enabled:
When the tunnel is brought up, the default route for the tunnel interface cscotun0 ist not set. So there is no IPv6 traffic over the tunnel possible. Manual adding of the route works, but is not what we want out user to do ervery time they log on. In Version 2.4.1012 everything works as expected.
Anybody out there to confirm this?
Compared to Release 2.4.1012 the routing table (ip -6 route) misses the followinf entry:
default dev cscotun0 metric 1 mtu 1350 advmss 1290 hoplimit 0

if you are able to use the latest 3.x client you will be fine. This resolved my problem. Version 3 is available for download on CCO. I can reproduce your problem with the missing default route in Version 2.5.0217. Otherwise you have to add the default route manually or use 2.4.1012.
We have configured the outside and inside Interface with official ipv6 adresses, set a default route on outside Interface to our router, we also have definied a rule , which also gets hits, to permit tcp from inside Interface to any6.
In Syslog I also se...
