Unable to access Collaboration 10.5 network via 881W VPN

I've been using a Cisco 881W router with a Cisco-supplied config to make an Easy VPN connection to the sandbox (a Collaboration 10.5 lab in rave08).  Everything has been working fine for the last two days, until a couple of hours ago when I lost access to the sandbox network (e.g. CUCM on fails to respond to ping and HTTP, Windows DNS Server on fail to respond to ping and DNS).  I can access CUCM via, so the instance itself seems healthy.


As far as I can tell there have been no local changes which would have affected this, and the lab has 1d18h left to run.  The 881W's VPN light is illuminated and tracert gets as far as before timing out.


I'm wondering whether the VPN group, key etc. are wrong, but the fact that it has worked for two days would suggest not.  Is there a definitive reference for what these should be for a given lab / rave?  Are there any current issues which might explain what I'm seeing?
